Interesting.  I was asking originally because Dan Wells asked me about
it.  OIT is trying to set up a pxeboot system for campus that works in
conjunction with their existing dhcp server.

He indicated that altirus worked by responding to the dhcp request, but
without a lease.  The host would receive 2 dhcp responses, one with a
lease, and one with pxe info, and figure out what to do.  At least
that's what he claimed.  Your explanation sounds more logical, though.
