erlang is an excellent choice for something like this.  a word of advice:
if you're looking to build a production quality service, make sure you 
build it on top of otp, rather than rolling your own.  otp can seem a little
daunting when you're first starting erlang, but it's well worth the effort if
you're building serious systems.  the docs are pretty good, and there 
are some good tutorials around now.  i wish i'd gone this route when i started.
would've saved me a lot of effort, and resulted in a much better system.

if for some reason you can't use erlang, twisted is a very nice framework
for building network servers.  i can't speak to its scalability, though.  no
experience with that.
