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 On Fri, 2007-11-09 at 20:18 +0000, Rob Beard wrote: > Simon Williams wrote: > >> Yep, good old XCOPY.
