Best lightweight linux IRC server for a team

I have not worked with a IRCd in a while, but from my past experience if your running a small capacity IRCd then your not going to be using up alot of system resources where as a large capacity IRCd would use up alot of system resources. My suggestion would be either InspireIRC, UnrealIRCd or UltimateIRCd because they give you the option of what modules to run with the server.

I know its late in the game to get in on this answer, but I have recently been looking at doing this myself, and found these two options as well:

https://github.com/jrosdahl/miniircd

http://ngircd.barton.de/

Both seem quite simple to setup and use and lean by skipping most features that a small/private IRCd wont need...
