Either the client or server would need to send a command to the other user/client in order to initiate multisource.

The problem doesn't really have anything to do with how servers comminucate with clients or how clients talk to each other.
OpenNAP allows you do initiate many diwnloads at the same time. That's not a problem.
OpenNAP allows you to initiate many downloads for the same file from different sources at the same time.
OpenNAP allows you to resume a file from any source. That's not a problem either.
As someone noticed earlier, when a multisourcing OpenNAP client came out, the trick may be to request multiple file resumes (so other clients understand it), and break the download when a certain point is reached, so the blocks don't overlap. Voila, you have multisourcing in OpenNAP.
I think the problem is being able to tell whether two files on different clients are really the same file.
