Oops, I didn't pick up at first that you said you have cable. That means you prob. also have a 256 kilobit per second outgoing pipe - figure you can host a game of 5 or less if you cap the player rate at 8000 (which is in bytes per second). You could squeeze a couple more in if you dropped the rate cap even lower, but less than 5000 and people are going to complain about the quality of the connection.
