I would suggest you stay away from wxIdle events, if only because they 
only occur under certain circumstances (in Windows, they seem to only 
occur when the mouse is moved over the window).

Start with asyncore, and get everything working properly with that.

When it is working properly, do something like the following for your GUI:

import asyncore
import yourasyncorelibrary

         #in the __init__ method of your main window class
         #set up the server/clients/whatever

         #using the new namespace
         self.timer = wx.Timer(self, wx.NewId())
         EVT_TIMER(self, self.timer.GetId(), self.SocketPoller)
         self.timer.Start(10, wx.TIMER_CONTINUOUS)

     def SocketPoller(self, event):
         asyncore.poll()

If you properly designed your server and clients, the above should just 
work.  If you are willing to post information about your architecture or 
protocol, I may be able to help you more.
