Out of curiousity, what kind of testing have you run, and what kind 
of speeds are you getting?
I've got a configuration with DomU talking to Dom0 over a vif, and seem to 
be seeing UDP losses, even at low data rates. (I haven't dug into this 
deeply to very the problem yet, though.) So I'd be interested if you're 
seeing something similar.
Thanks,
