Indeed. And in this case, sharp instruments need to be kept well away
from the children. That means avoiding some of the obvious rat-holes
when it comes to DNS administration. Note too Niall that lots of ISPs
can't get RFC2317-style delegation right and these are the guys who
should have DNS skills as a core competency.

Long enough to kill off ENUM by making it seem less robust and
dependable than it could be? Consumer confidence is going to be
critical for ENUM to become widely used. Cheap calls over VoIP may get
everyone's attention. But if DNS lookups fail and phones don't ring
reliably, nobody's going to use it.
