A cisco box can - with two serial ports (I'm not sure they will keep
up with two 2Mbit ports going hard simulataneously, but it looks
like it should).

Oh... not so easy to make work then.
As I said before, I'm not saying it fair to expect a generic linux
kernel on generic hardware work as well as these systems, but since
we have a bigger processor (generally speaking), we can hopefully do
pretty well - and its a goal worth going for IMO.

best...
