Facebook working on Jabber chat

First of all let me explain what Jabber chat will let a user do.
Jabber chat basically opens up Facebook's chat and allow it to be ported (used) on chat programs like AIM, MSN or mostly multi protocol chat services (see post here).
Basically Facebook chat will become bigger as it will be easily possible to integrate it with the same contacts you have on MSN, AIM and others.
To give it an edge over other chat methods, it will allow users to update status, see their friends profile picture and probably more (im guessing messages, wallposts and such). Basically facebook is going to gain a more prominent spot in the instant messaging world
