Am I missing something, or is enum a nice technical solution which can, almost by definition, never be deployed?
enum itself can easily be deployed: there's no reason an alternative enum registry couldn't be built under e164.*.nz without needing any permission from anyone.
You're correct, it can be easily deployed - I had a test bed e.164 zone while I was doing some work on ENUM a few years ago. There is also a shared secondary domain that anyone can register phone numbers in: http://www.e164.org/ I haven't registered any zones in e164.org yet - my crappy ADSL router locks up whenever I do ENUM lookups over it (but DNSSEC works, go figure). A replacement is on the cards.
The only drawback is that software wouldn't be preconfigured to look there, but how much software already looks at 4.6.e164.arpa anyway? I don't work with VoIP every day, so maybe e164 has been widely deployed while I wasn't looking, but I'd be surprised...
Most software that I've played with can be told which zone (or multiple zones) to look in. If you're used ENUM for internal call routing for a PBX then you'll have an internal zone as well as e164.arpa (or e164.org).
