With the popularity of Facebook Chat this was the obvious next step. Turns out that Facebook chat is now compatible with the Jabber protocol meaning that it can be connected to using a Jabber client. This means that BeejiveIM and IM+ should now be able to connect but no promises. If they don’t already work they probably will support it soon…
I have not been able to find a ton of details on this but eBuddy already supports Facebook chat. You can pick up the eBuddy client with Facebook chat at get.ebuddy.com but I have not had a chance to try it myself to see if it works.
Just a heads up!
