ThreadingTCPServer, asyncore and Client-to-Client communication

[Dustin]

I've been trying to create a "byte streaming server", it's basically a
chat server, but I'd like to use it for transfering large amounts of
data between two connected clients.  Sounds simple enough, but I'm
having a difficult time implementing it.

If Client #1 connects, then that thread is consumed with listening for
data from that client.  If Client #2 connects, that client is on a
different thread, and therefore I don't see how I can have data sent
from Client #1 to be streamed down to Client #2.  (and how can client
process #1 accept data from client #2 because it's listening to client
#1?)  Obviously I'm missing something.

I've looked at asyncore/asynchat, as well as ThreadingTCPServer... but
there's something I'm missing.  Is there a simple way to have an
object listen over two ports, and what comes into one port will be
sent down the another?

Any advice, or a good swift kick in the right direction would be
appreciated.
