Investigate options for IRC lib
Currently using node-irc - https://github.com/martynsmith/node-irc
This does not support all IRC commands, and seems to be more tailored to bots than clients.
Other options:
irc-framework - https://github.com/kiwiirc/irc-framework Based on kiwi IRC code, designed for clients and should have good coverage of IRC commands, but seems to still be a work in progress of ripping the back end code out of Kiwi IRC
slate-irc - https://github.com/slate/slate-irc Used by slate and shout web clients, looks to have good coverage, has plugin support
TheLounge (fork of shout) switched to irc-framework over slate, so this is probably the best option.
Alternatively, write my own...
