BitlBee allows users to talk to people on the major instant messaging and microblogging networks (including MSN, Google Talk, AIM, and Twitter) from within any IRC client by emulating an IRC server. Virtual channels are created with all of the user's contacts in them, who can be talked to in the channel or in a query. Also, one can participate in group chats and chat rooms like they were normal IRC channels.
AIM Sniff is a utility for monitoring and archiving AIM and MSN messages across a network. It can be used to monitor for cases of harassment or warez trading. It has the ability to do a live dump (actively sniff the network) or read a PCAP file and parse the file for IM messages. You also have the option of dumping the information to a MySQL database or STDOUT. AIM Sniff will also monitor for an IM login and then perform an SMB lookup on the originating computer in order to match NT Domain names with IM login names (handles).
