I've tried this before and binned it due to the mess MSN creates on your googletalk contact list, but here I am again re-connecting my MSN Buddies to GoogleTalk...

Connect Google Talk to AIM, MSN, & Yahoo - BigBlueBall Forums
Now that Google has opened up their Google Talk servers for federation with other Jabber servers, you can use Google Talk to connect to your friends on AIM, MSN, Yahoo or ICQ.

I don't like MSN, the client is clunky, full of adverts communication is insecure, blah blah blah; so I stopped using it daily (i.e. singing automatically) a couple of years back, but my stubbornness of asking my friends to switch to googletalk or skype has only back-fired, in some cases I have even lost touch with people, this is complete madness since some my "buddies" even have gmail e-mail accounts!

I really wish that MSN,AIM,ICQ,GoogleTalk and everything else would implement a "gateway to gateway" standard, the idea of having to create gmail accounts or hotmail accounts to send e-mails to specific buddies is considered madness so why isn't there an implemented "SMTP" for chat, google have obviously started the ball rolling by using XAMPP as their standard but why won't the others play ball?? Come on guys sort it out!!!!!
