Re: Admitting Opcode discover draft?

["Scott Rose" <[e-mail]>]

I guess you could call this an objection:

>From reading the DISCOVER query draft, I got the feeling that it would
almost become a lightweight resource discovery protocol.  Much like SLP,
only with fewer features.  Do we really want to mangle DNS to make it do
resouce discovery?  (the section of using QTYPE = SRV is what I'm talking
about).  Discovery of DNS servers would be the best use of this new query
type (and keep it limited to that).

If the rest of the working group want to adopt this draft, I can live with
it, but it my vote is it's re-inventing the wheel and forcing DNS to become
a service/resource discovery protocol (which should be avoided).
