No.

The original thought was that it wouldn't be required for the sort of 
use-case dnsmasq is designed for. A small router would _receive_ and 
delegation, and then hand out addresses from the range. Given that the 
IETF homenet WG seems to be moving towards recursive PD within a 
homenet, this may have to change. I don't anticipate it happening soon 
enough to solve your immediate problem though. Sorry.



Cheers,
