I would like something that could replace Tormail this year, and that relies on no central server. That is Torchat's greatest strength. Nobody can take it down or overwhelm the network / server, like what appears to happen to Tormail every time there's a database error. The trade off is that Torchat is a live messaging system. Both parties must be online at the same time. If it stored messages like BitMessage, that would be perfect.
