Calm down. It's a serious question. Given that Xen is good for some 
things, and I use it for some of those, the adventures of going through 
the iptables adventures to get that working, and relying on the Dom0 
hardware as a single point of failure seem excessively painful. If 
there's a good reason to do so, I'd love to hear it.
Also, given such a desire and the routing/firewall adventures possible, 
which still lack good documentation, I'd encourage the original poster 
to consider if they want to have this adventure or be the one to write 
it up. Given the difficulties especially with USB devices and the 
firewall issues, I wouldn't want to take that on as a newbie.

Perhaps I was too dismissive: if it's just for the fun, cool, and good 
luck with getting the PCMCIA or USB integrated.
