[Haskell-beginners] command-line interaction with running process

[Sumit Sahrawat, Maths & Computing, IIT (BHU)]

If you decice upon the server-client architecture, you should take a look
at zeromq.
It is used extensively in IHaskell, so you can peek at the code there for a
working example.

Also, I believe a client-server architecture will be better as I personally
enjoy games a lot more when they are multi-player.
It makes the conversion from single-player to multi-player a
non-destructive (or atleast less destructive) process.
