In defense of Keith it was a meeting of those persons who had current or
pending proposals. It was not meant to 'circumvent' the URN group but
instead to see if several of the competing proposals had any common
ground on which to build on. A few of us made some compromises and we
came up with a proposal. Its just that. The only weight it carries is
that each of the attendees is going to modify his/her proposal to
accomodate the compromises.

No. It suggests that Ron was also at the meeting and that this document
also contained the announcement as an action item.

DNS can be used for SOME things. As long as its used for what its good for
and nothing else. I've been noted as being one of the more vocal against
DNS. I support this proposal. It limites DNS usage to what its good for.
Personally, I think the path schemes extensions of this are a problematic
but that is a fallback algorithm that is specifically not discussed here.

I agree that it needs to be left to URCs but you can't ignore that
it is important to key members of the community.
