Re: [LUG] Traffic Management was XCOPY was OT: Why oh why windows at work? . . . File copying

 

Alternatively have you tried MLPPP bonding ?

If you really want more bandwidth how about bonding two BT Max adsl
lines through a linux router box using Eddie Chapman's software

see http://www.upstreaminter.net/bondedcd.shtml

It's a nice idea but not exactly on the cheap side
