I created an "Interface Manager" that encapsulates each IM service. It currently works with MSN, Oscar, Jabber (those are the services my bots connect to) and also supports IRC, AIM and CMD (however, those are much more limited). I built it over a year ago and haven't touched it since, but plan to start fleshing it out more soon. It allows you to create interfaces, passing in connection info, and then add them to the manager. With this, you can connect to multiple IM services at the same time or use it to "load-balance" your IM users across multiple bots on the same IM server. It's still fairly rough around the edges, but works and you can use it, get ideas from it and hopefully give me some feedback. Download it at http://www.botwork.com/downloads.html
