IS> By how much?  Maybe they also upgraded other hardware and/or setup too?
 My ping went from 200ms to around 170ms, you can notice it in the game..

IS>    75 * 10 / 28800 = 26 milliseconds.  At 33600, 75 * 10 / 33600 = 22 ms.
IS> So both ways you might expect an 8 ms improvement due to the higher rate,

 Ok, lets say QUAKE,software etc takes 50ms, that leaves ya with 150ms due to
data being delayed.  So you have 150ms for a 28k8, 128ms for 33k6 and 72ms
for 57k6

IS>  SA>  I say, Yes, V.Mach will help, HEAPS...
IS> A few milliseconds, as far as RTT times for short packets go, anyway.
 I have seen people on QUAKE with a 90ms ping, yes, they are not on a modem 
but they where not local to the server :)

 Cya!
