I'm curious to see what type of pet project you're cooking :-)

The Dion DSL service that some family here had a few years back had DHCP
lease times that I informally measured in hours.

One option you could do is to write a script to do the following and see
if that helps.  I imagine you could do something similar if you need  
to use
PPPoE although add steps for the authentication process.

Every arbitrary time interval
1. Release DHCP lease
2.  Change your mac address to some different value
3. Try to re-acquire a IP address via DHCP
