We can take comments towards a -06 over the weekend. The most substantial changes are in the Naming and Service Discovery section (3.7), so if you have limited time please focus your reading there.
One thing that I'm not sure whether it's been discussed or not is service announcement. By service announcement, I mean where instead of multicasting out a message looking for the canonical printer with all of its nasty properties especially for things with batteries and lossy/slow networks, a device would instead announce its presence to something that would later serve it up (eg, bind9, say). That is, if we can posit a dns repository in our home edge routers, we can avoid some of the insanity that ensues when you say that something MUST be strictly zeroconf. I think we are long past the days where strict zeroconf should be the driving principle; littleconf should be a valid option too. Service announcement could also feed into things like Search where instead of having preset categories which make sense perhaps only to those who chose the category at the factory, we could also have structured and/or free-form text with lots of keywords and other identifying information that an indexer might find useful. Mechanistically, we already have things like IXFR for DNS, so it's not likely that this is wholesale invention, though it may well involve some tweaks. IXFR also gives the possibility for enrollment and access control which is pretty problematic with service discovery.
