Well yeah
(in the future me hopes!)
But I don't think they need an overly stout connection though. It seems to me, at least in my testing, that the maximum upload/download connection at any given time regardless of the number of players is always less than 70kb to the client. The server with 30 people on it, is only streaming around 1.5 to 2mb of upload as well (with download a bit lower than that)..
