I guess what I'm getting confused about is how to get my listen server
(MUD server) talking to this IMC client connection. Let's say one of
my player wants to send a message over the IMC (client) connection.
This is done by telnetting into the MUD server and entering a command
like: imcmessage "hello". So I've got a reactor serving up my MUD
server process, and I'm not sure how this IMC client plugs in.
I guess I need to create some kind of queue that the IMC
ConnectionMade checks periodically and executes if I can't directly
get the MUD server talking to the IMCProtocol object.
Also, do I need to do anything special to prevent blocking?
Do I use two separate reactors or should the IMC connection be using
the same reactor or process group as the MUD server (listen server)?
Thanks for your help. I'm sure this will be really simple to do once I
figure out how to do this.
