[Twisted-Python] Vertex or other P2P libraries for twisted?

[Vince Cate]

I would like a library that I can use from Twisted to help with
peer-to-peer communication.  I have looked at and tried Vertex:

  http://divmod.org/trac/wiki/UsingVertex

This is the kind of thing I want.  But I am having some problems with
it.  Are there other similar libraries out there?  What are people
using?

The problem we have with Vertex is sending from Windows to Linux.  We
can do Linux to Windows.

The error we get is in file ptcp.py
in class PTCP
def connect(self, factory, host, port, pseudoPort=1)
with factory <vertex.q2q.RPTCPConnectionAttempt instance at 0x010CEBE8>

Any help appreciated.
