Can you elaborate on this? My only issue with the kernel route balancing 
is that route caching can not be disabled entirely, so traffic to the 
same site will leave via the same channel, regardless if the other 
channel is empty or not. I know that it is technically possible (kernel 
option CONFIG_IP_ROUTE_MULTIPATH_RANDOM), but it will work only for 
globally routable addresses, while breaking NAT badly.

The reason I made my bold, as you call it, statement, is because 90% of 
the time when someone is doing NAT, it is for a tightly joined group, 
with similar interests - hence a lot of traffic duplication. For 
instance if every user listens to the same online radiostation - how 
would you work around it?

Let me know your thoughts

Peter
