  My uplink is 768kbps (kil bits per second) which I think is about 768/8
= 96KBps (Kilo Bytes per second). So I still have about 40KB left for
band width.

I have measured my bandwidth to be about 3KB-4KB on a 100mbps LAN hooked
to a switch with the server -- both are in full duplex mode. When I do a
status with RCON my PC's rate shows to be 30000. Is this is in bits or
bytes ? If it is bits, then 30000/8 = 3750 which reflects the measurement
of 3KB-4KB I did above.

Assuming a *cough* 'perfect' connection from clients to my server on the
cable modem. 768kbps/30kbps = 25 players -- 'MAX'.

Pretty lucky indeed...;)
