Don,

Yes, based on, and it will be good to see those RFCs out.

What I'm basically worried about here is ending up with one
toolset for homenets and a different toolset for small enterprise
networks, which seem much more likely to go the DNS way than anything
else. In practice there's no hard and fast boundary between home and
small business.
