I've considered it, and in an ideal world would like to implement it.
My experience is the _nothing_ to do with DNSSEC is "not too
difficult" and, to be honest, any system deploying the releases of
dnsmasq with DNSSEC to-date which can't be updated is in a bad way
anyway. I hope we're close to a stable implementation now, so maybe
now is the time to start thinking about this. Of course this is only
relevant of the root key really does get rolled sometime soon, and if
that doesn't cause the end of world.

My ideal would be to a have a stand-alone RFC5011 daemon, which is
responsible for keeping the OS's idea of the root key(s) up-to-date.
Debian already has a package which provides a central copy of the root
keys, and dnsmasq will use these is it's installed. Having something
which does that but dynamically updates them would be good.

Cheers,

Simon.
