I'm not sure I fully understand your questions.

dom0 feeds each domU's console input.  The current source of that input 
is a TCP socket via Xend.
All network traffic is funnelled through the network device's backend 
which currently lives in dom0.

It depends on what you're trying to do.  If you want to do some sort of 
traffic shaping or routing the normal Linux hooks should work in dom0.
If you want to trap console input, you're probably going to be looking 
in Xend.
