Live Profile and Jabber

I've recently heard of this new thing called "Live Profile".  Essentially it allows Android, Blackberry, and iPhone to communicate with each other with text messages... without the need for clunky sms.  It's all fine and dandy, and I think it's a good program. However, for my purposes (because I use a Nokia n900) I prefer the Jabber protocol.  It is open source and works on lots of different platforms. Furthermore, if you have a Facebook account and use chat, you automatically have an XMPP (which goes hand in hand with Jabber)

Have fun!
