Well, at least with DNSSEC, you can assure the end user that the
wildcarding was intentional (through validation), I dont see why those
systems shouldn't be acceptant of intentionally obscured hosts in the
future ?

Saying that, I quite like the idea of dynamically providing a response
to both AAAA and PTR queries but question how safe it would be to cache
these without a robust resource-managing implementation...
