What is claimed is:
1. A method comprising:
receiving a service request;
fulfilling a portion of the service request; and
requesting a remaining portion of the service request from a peer.
2. The method of claim 1, wherein requesting the remaining portion further comprises:
creating a partial response to the service request.
3. The method of claim 2, wherein requesting the remaining portion further comprises:
creating another service request; and
including the partial response in the another service request.
4. The method of claim 1, wherein requesting the remaining portion further comprises:
sending a registry request to a registry server.
5. The method of claim 4, further comprising:
receiving a response to the registry request; and
choosing the peer from a plurality of peers in the response.
6. The method of claim 5, wherein choosing the peer further comprises:
choosing the peer based on geography.
7. The method of claim 5, wherein choosing the peer further comprises:
choosing the peer based on price.
8. A peer comprising:
a controller to break a service request into a first and second sub-requests, complete the first sub-request, find another peer, and to send the second sub-request to the another peer.
9. The peer of claim 8, wherein the controller is further to send a registry request to a registry server to find the another peer.
10. The peer of claim 8, wherein the controller is further to create a response to the first sub-request and store an address of a requesting peer in the response, wherein the requested peer initiated the service request.
11. The peer of claim 10, wherein the controller is further to embed the response in the second sub-request to the another peer.
12. A data structure stored on a machine-readable medium, wherein the data structure comprises:
a header field to store an address of a second peer;
a response field to store an address of a first peer and a first sub-response to a first sub-request, wherein the first sub-response is created by the second peer; and
a request field to store a second sub-request for service from the second peer to a third peer.
13. The data structure of claim 12, wherein the first sub-request and the second sub-request are components of a service request from the first peer.
14. The data structure of claim 13, wherein the second peer is to break the service request into the first sub-request and the second sub-request, perform the first sub-request, and store the address of the first peer in the response field.
15. A response data structure stored on a machine-readable medium, wherein the response data structure comprises:
a header field to store an address of a third peer;
a first response field to store an address of a first peer and a first sub-response to a first sub-request, wherein the first sub-response is created by the second peer; and
a second response field to store a second sub-response to a second sub-request, wherein the third peer created the second sub-response.
16. The response data structure of claim 15, wherein the second peer created the first sub-request and the second sub-request from a request.
17. The response data structure of claim 16, wherein the request originated from the first peer.
18. A signal-bearing medium comprising instructions, wherein the instructions when read and executed by a processor comprise:
fulfilling a service request, wherein fulfilling the service request further comprises creating response data;
creating a response to the service request;
copying a partial response from the service request to the response; and
inserting the response data in the response following the partial response.
19. The signal-bearing medium of claim 18, wherein the instructions farther comprise:
sending the response to an electronic device, wherein the electronic device is identified in the service request.
20. The signal-bearing medium of claim 18, wherein creating the response to the service request further comprises:
creating a response header comprising an address of a peer that creates the response data.
21. The signal-bearing medium of claim 18, wherein the partial response comprises an address of a peer to receive the partial response and second response data from a partial request.
22. An apparatus comprising:
a server comprising
a registry comprising identifications of services and identifications of peers that perform the services; and
a second electronic device to receive a service request from a first electronic device, to fulfill a portion of the service request, to find a third electronic device using the registry server, and to send a remaining portion of the service request to the third electronic device.
23. The apparatus of claim 22, wherein the third electronic device is to fulfill the remaining portion of the service request and to send a response to the second electronic device.
24. The apparatus of claim 23, wherein the third electronic device is to fulfill the remaining portion of the service request by itself.
25. The apparatus of claim 23, wherein the third electronic device is to use a fourth electronic device to fulfill the remaining portion of the service request.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A cell culture comprising 1) an oligodendrocyte progenitor cell disposed on a polymer material, wherein the polymer material comprises an acrylate or a diacrylate; and 2) a culture medium.
2. The cell culture of claim 1, wherein the oligodendrocyte progenitor cell is a human oligodendrocyte progenitor cell.
3. The cell culture of claim 1, wherein the oligodendrocyte progenitor cell is derived from a human embryonic stem cell.
4. The cell culture of claim 1, wherein the oligodendrocyte progenitor cell is derived from an induced pluripotent stem cell.
5. A cell culture comprising 1) a progenitor cell expressing Nestin and Olig1 disposed on a polymer material, wherein the polymer material comprises an acrylate or a diacrylate; and 2) a culture medium.
6. The cell culture of claim 5, wherein the progenitor cell is a human oligodendrocyte progenitor cell.
7. The cell culture of claim 5, wherein the progenitor cell is derived from a human embryonic stem cell.
8. The cell culture of claim 5, wherein the progenitor cell is derived from an induced pluripotent stem cell.
