Microsoft showed the source code to the MARID group. It simply does not

Someone in the DNSEXT working group did a test that showed that if you
violate the administration model of Windows it is possible to emit the
correct bit strings for new RRs. But that is not a method that any
competent system admin would accept in a production service.
First of competent sysadmin would not run his dns server on windows
(I'll be flamed hard for that statement...) and second if MS really
wanted to they could release code to support new records in binary
(or even specific ones) as part of their servicepack cycle (they in
fact do protocol support updates for their other products if its
something missing and necessary) and whoever needs to host this RR
on their system with MS DNS server would get this update.
Since you were at MARID you should remember that issue that thought
to be more serious was not MS DNS server but MS Proxy server which
is apparently very proprietary and only works with MS clients and
communicates with them by converting DNS into RPC calls (or something
of the sort - whoever knows more about this weird thingy can correct
me). Unlike DNS the support the update of this would require changes
in both client and server that are deeper and this proxy server also
seems a lot more in use then actual dns server for hosting internet
domains. Info on updates to this piece of software to support unknown
DNS RR types would be most welcome.
