Ja dat kan. Je moet hem dan koppelen via een externe service zoals bijv. jabber.hot-chili.net Dat heb ik zelf ook gedaan en het werkt perfect
1. you need a google-account
2. you need a software like gajim (available in Ubuntu Software Center)
3. in gajim:
a) login to your google-talk account
b) under action -> services type "jabber.hot-chilli.net"
c) find the msn/windows live-transport and add it to your google talk
d) follow the steps and use your live account details to login
e) now facebook-chat is integrated to your google-chat account, independently from the software. You can verify that by going to your googlemail account. On the left side you will see your google-talk buddies AND your windows live-buddies.
