I guess if you'd use multiple connections to the same ISP (and same 
access point) that would solve the problems of different RTT values.
Otherwise i can confirm there are problems, i had a lot more (needless) 
retransmits using a dsl + two isdn links which was probably due to very 
different RTT on both links.

It's not always practical. For example in my case one of the links is 
asymetric (256k upstresm/1mbit downstream), the other isn't. So 
distributing traffic with a normal multipath route would result in some
connections (maybe downloads) beeing on the link with slow downstream.

Bye,
Patrick
