[Richard>] Yes, these a clever guys ;-)

No Jim, KISS.

Easiest thing to do is query one tree after the other, first ENUM and then
Infrastructure ENUM. If you get an answer in ENUM, you are done, no
arbitration necessary.
As I said: Infrastructure ENUM is the equivalent to "dump the call to the 
PSTN".

I also said here on the list many times: they do it already with e164.arpa,
freenum.org for 800 numbers and then to the PSTN (1 2 3). As a user I just
dial a phone number. BTW, freenum.org is very convenient for long phone conferences with the US, this is a service the PSTN cannot provide.

No problem whatsoever.

Richard
