Installing a chat button

Can BHW install a chat feature like facebook? Like anyone can chat with another person when both of them are online... It would be really cool, as PMs sometimes takes ages to get replies, and not everyone lists their AIM/ICQ/YM/MSN

Toyo, why not just tell the person to meet you in the chatbox,

Then go into PM chat with the person from there ?
