The Phweet alpha service launched making it possible to talk to your Twitter friends. Here's an excerpt from site "Sign-in with your Twitter name and password at http://www.phweet.com/. Select your preferred channel (Browser, SIP ID or number/Mobile Phone which will be enabled later) for hosting/accepting a Phweet. Add the Twitter username of the person you want to talk to, and send them a message (public or direct/private)." This is service by Mosoci LLC, the strategy and research group that also does the Skype Journal and is heavily involved in VoIP applications.
