I really don't think anyone is doing that. I've been chatting with 
somebody from Apple and somebody from ISC about having mDNS interfacing 
with DNS (BIND), and both were very keen on seeing that happen.
If some vendors did it in their proprietary code with their proprietary 
DNS servers, good on them :-).

I would certainly love to have that :-)

I agree on that. That's what I was trying to achieve here at CAIA, but 
never got the dnsextd to work which should do the mDNS to DNS 
translation, nor had the time to implement a counterpart in Avahi.
BIND doesn't need to be changed, as it would be the same mechanism as 
secure updates via DHCP.

Maybe somebody has done something in the meantime (my info is from 
December last year).
