It would be awesome to see valve locking some of those stupid cmdrate/updaterate/interp vars too - most people don't have a clue what they do exactly, they just think "higher is better". Also, why does everyone think "rate 25000" is enough for a 2mbit connection? I have set mine to '999999' as it's just a limit - i have never seen source exceede 80kbyte/s, which would even fit into a 1mbit connection.
