I was asleep when the announcement was made, but you can download an MP3 of the announcement and interview Here.
Basically Supernova's project is a new P2P program like Kazaa, but for distributing torrent files, thus eliminating the need to find a torrent site that lists the file you want. All the downloads through this new program (called Exeem) will have ratings and comments available from people that already have the file, so this does look like to be the next generation of P2P programs.
The beta will start in a few weeks and details will be posted on SuperNova and the soon to be opened Exeem Website.
The only thing that bothers me is that this is being developed by a company that doesn't want to reveal its identity yet. Eventually they will have to, but I find the secrecy a little suspicious.
