if such out-of-baliwick glue was in part of a signed heirarchy itself
-AND- the local system attempting the validation had associated Trust Anchors
for those parts of the signed heirarchy...

so for the dnssec trust model, self-signed or third-party signatures are
not to be used/trusted. but does this lema preclude the existance of
such signatures?

dns (and dnssec) have been inthe process of "endless design and redesign"
since their inception. i'm not asking for anything more than status quo.
if you -WANT- the kind of funding that supports and encourages research
(where its ok to have novel ideas that may not fly in the commercial world)
then that kind of funding is there... but there are downsides... as is
true w/ nearly all funding models.

dns was never frozen while it was being deployed. and i suspect dnssec
won't be either.
