webcam like conference


this is a big question.
I have a game ( like scrabble ) with 4 players at time.
I would like all each player in game see others players through webcam.
I have an application game sever for hosting each game and translate messages.

what is the best solution to do this ?
another application with upd ? another hosting server special for this type of communication ?
