The winners of the Imagine Cup 2007 Software Design Challenge are a Team 3KC Returns from Thailand with their entry Project LiveBook!
The only bit of information I could find on the team is within Google cache, with the only thing interesting detail being the integration into Wikipedia and Encarta.
Channel 8, the new student portal from Microsoft, have done a series of videos from the Imagine cup, sadly Thailand or the UK are not online yet.
Well done to all the teams who have won, especially Ireland who made it into the last 6.
