Very Odd: Google Doesn't "Talk" About Opening AIM Here

Mike Jazayeri, Google's product manager for Google Talk, talks about opening up Google Talk, allowing other clients to work with it so we can all communicate on whatever IM client we wish, which I think might be news that has been recycled from before.

Not sure what difference this has from earlier discussions about using this cool open protocol called XMPP. Oddly, he doesn't mention the AOL-Google relationship and what this means to Google Talk. It does reference using SIP in the future, though am unfamiliar with if that is AIM's proprietary protocol. I don't think so, that's a guess.

From what I understood AIM will now be compatible with GoogleTalk. Just wondering why this wasn't mentioned here.
