Yep, that's the hack I was getting at.

As a non-technical end-user, once my CPE has got a prefix from my ISP and advertised it to the devices on my LAN, the same prefix should keep working until:

-my ISP assigns a different one
-the end of time

whichever comes first :)

Having my PC not be able to talk to my printer any more because my DSL / cable / wimax / whatever has been down for "too long" is not acceptable.

Tim.
