I have researched this issue in the past. It is very difficult to make
wx apps listen to an arbitrary file descriptor, however, they can respond to 
generated within the libray (wxSocket class) with normal events.

Problem is, the XML-RPC server in the Python libraries does not use a wxSocket, 
it uses a 
'plain' socket, a similar problem exists trying to listen for traffic on 
postgres connections.
A blocking background thread which invokes an event in the main thread may be 
the best solution.
