That is definitely *not* what I want to do.

I want to make the server as generic as possible, so that it can handle any
type of client, hopefully even including a browser eventually. Therefore the
server has no knowledge of wxPython event types.

I have abstracted all the event types I am interested in (the list is fairly
stable now). My protocol requires that the client maps a specific gui event
type to a message identifier, and the server maps the message identifier to
a method that handles the message.

Hope that makes sense.
