The basic issue, as I understand it, is that zone operators don't want
to serve the DNSSEC-enabled zone from their regular name servers.
They'd rather want to set up a completely separate infrastructure.

Stephane can probably explain it better.

I would rather see resolvers made authoritative for the lookaside
zones.  From a privacy point of view, this is preferable because
queries don't leak to new parties.  On the other hand, this makes it
more difficult to release emergency updates.

I not sure if DHTs are the answer here because we deal with
intrinsically bad records which might have been devised to trigger
algorithmic complexity issues.
