@cs4 100Mbps is the available bandwidth.
I did a few tests with a 38.4Kbps mobile connection, and it can sustain games with up to 6 players. Which means about 6.4Kbps per player.
You can't really say that our server can sustain up to 100Mbps / 6.4Kbps = 15625 players, because the greater the number of players, the bigger is the amount of data sent to each client (position of every player, events of every player, etc...), anyway it's fair to assume that a we are way within bandwidth limits here.
