Thanks for your response.  Unfortunately I don't have control over the dhcp
server, so I don't think this approach will work.  What I need is a general,
programmatic way to get IP for xenU from xen0 in any situation.  I'm
creating an application for use in any environment, not just in my office.
Maybe there is no dhcp.  Maybe there is no dns.

After tinkering with this for a few hours, I'm starting to think it can't be
done without some sort of Expect or perl script to interact with the xenU

P.S. please send responses to the mailing list instead of directly to
individual subscribers, thanks.
