I think that if you just want to use the same setup as Tribler you can just directly use their code. What I'm interested in is separating and generalizing the various protocols involved rather than having them all knotted together.

Me too,

It seems like a logical part of that would be to have each protocol documented and encapsulated in a library.

Also, I'm working on a multi-protocol client which would aggregate a number of sources, so it would be especially nice to the have a library to call so that I could add one more source.

In any case, your work looks fabulous and I will spend some time digesting your links.
