I guess you can only go the other way. Let the clients call some script
on the server to update their ip. Dhclient3 has hooks which you could
use, but you had to configure every client for this...

I wrote some cgi script to update records in the mysql backend, you
could extend something like this for multiple clients and let
dhclient-exit-hooks curl it.

Bind supports rfc 2136. And i just looked at udhcpd which seems to be
able to call a script after giving a lease to client.
