Hi Andreas,
it's possible by using the 'script' attribute within the vif definition. 
The  xend-config just defines the 'default' script.
<code>
vif = ['ip=10.0.0.YZ-AB.CD.EF.GH, vifname=vps-name-pub, script=vif-nat-fw']
</code>

The vif-nat-fw is my own script which is configuring the NAT on the fly 
based on the IP pair defined by the 'ip' attribute. Of course you can 
also do the mixed setup with NATed and bridged domains.
For more information browse the /etc/xen/scripts directory.
All other questions are welcome. ;-)

Best regards,
