Bandwidth Throttling w/SSH, Local Loopback, RH9...

I got a serious hobby related problem.  I run a game server under Redhat Linux 9 which provides a great deal of traffic per user (somewhere close to the 28.8kbps per user upstream and 56.8kbps per user downstream) from the server.  Because of the nature of the game design and the network setup, I'm running under a local loop-back (token ring emulation) to allow an encrypted up/down stream via SSH for both client and server.  My problem lies in bandwidth per user.  The bandwidth continues to fluctuate and causes instability and latancy for many of my users connecting from the WAN.  Because this data stream is not object oriented (much like ftp or http), Squid seems like a dead choice. My server is currently hosting up to 15 players, but I am about to send the server to a co-locater which will allow it to host around 60 players.  This problem needs to be fixed, or I'm paying a great deal of money out of my pocket for bandwidth I know I can control.  Can someone help please?
