Yogurt[1], a MUD client, uses two threads: one to process input from the 
server and one to process input from the client. It uses an MVar to 
synchronize. All concurrency is located in module Network.Yogurt.Readline.

Custard[2], a MUD server, uses several threads:
* Server, maintaining MUD state
* one that listens for incoming connections
* per client, one that listens for client input
* per client, one that listens for messages from Server
It uses channels and message passing to synchronize. All concurrency is 
located in module Engine.

Hope this helps,
