From the developer:
Twee.li is instant messaging for Twitter.Talk to whom is following you, see their last tweets and DM them. Think of twee.li as MSN or GTALK, only using your Twitter account to chat in real time with your Twitter network. At this time there are giving away only 10,000 invitations due to server limitations.
