Are your users connecting from within a private LAN? Don't re-invent the wheel, 
use DNS. Just have your users pick a host name when they create their domU. 
Dnsmasq (http://www.thekelleys.org.uk/dnsmasq/doc.html) is a lightweight app 
that provides both DHCP and DNS services all in one package. This can easily 
run in dom0, or a domU specifically set up for the purpose.
