Best Kept Secret: Yahoo Messenger Plugin SDK

I think many folks who are doing web development have no idea that an amazing new platform for web applications has quietly launched with the release of Yahoo Messenger 8. Imagine if you could create a web application which had chat built in - and you didnt have to manage a buddy list, sign on, etc. Now you can create either tab plugins (that live under your buddy list) or conversation plugins (that live during an im session with someone). All using javascript and HTML. It seems like a incredible opportunity to combine web 2.0 with messaging. I know I have something cool up my sleeve soon. I've been waiting for this thing for years...

The panda golf game is really fun, and only scratches the surface of what you might be able to do with this SDK.
