Simon thank you for the answer,

OK so I'll put an if-up.d script in the clients to do the DNS update.

I can think of a clumsy way to do it, i.e.
1) The if-up script would use nc to send the info to the server,
2) An inetd-based daemon on the server would get the info and append
   it to an -addn-hosts file
3) And finally the daemon would HUP dnsmasq to re-read that file.

Any more elegant way to do DNS updates in our less-than-ideal use case?
