Sorry, the domu IP (10.0.0.x) is as accessible to the dom0 as 10.0.0.1 
is, being attached to the bridge. If you are forwarding and have the 
relevant routes:

dom0# route add 10.0.0.0/24 -link nfe0 -iface

domu# route add -host 192.168.1.100 -link xennet0 -iface

Then it should probably work fine :)
