Unfortunately, Meebo is like a portal, function as a mere doorway for the MSN channel to pass through, so we still connect to the MSN API directly. Unlike dabr.co.uk - for example - with the twitter; although the office blocks all twitter APIs, I can still use all my twitter features via dabr, because it collects data from twitter, processes it, and presents it to us, so we actually connect to dabr, not twitter. Or the Ping.fm, which takes our messages, processes it, ad relay it to our social networks.
Well, how are you doin, buddy? I'm not very good right now, got some bad news. Care to lend an ear?
