Hmm...regarding the new RR, the only thing I can think of today is the need for some changes in the provisioning system from which one create the DNS zones. I do not know of any DNS code today that can not handle "unknown" DNS RR Types, but maybe I am wrong? I am though confused over (1) as this is 2010 and not 1998.

Regarding (3), I think it is sad people move redirects and lookups and functionality to be on top of HTTP instead of IP. And I do not understand "in the absence of DNS"...that is an interesting situation ;-) Specifically to use that as the foundation for the architecture to use for calendaring, that is -- I hope -- one of the more fundamental applications on the Internet.

A new version of my draft I promised today, but due to this security consideration discussion, it is now delayed yet another day.

And yes, I will do the job of releasing a new version although there will continue to not be any interest of using it. :-)

Or maybe I should just push it through, although for calendaring draft-daboo-srv-caldav will be used. Hmm... I do not want to be problematic here.
