Are you going to have our CNAM stored in a LIDB system?

Could you make your sign-up process include a field for "CNAM DISPLAYS AS: _____________."

I know you don't want abuse. If it is only set on sign-up, then there is less likely abuse.
If it could be changed often, you invite abuse.

I would like <first-name> usa2k <last-name> as CNAM if possible.

I ran my number here as a test: http://www.cnam.info/
It had the correct <first-name> <last-name>
My number was LNP: Vonage => Packet8 => VOIPo
(The LIDB could have been set at any of these stages.)
