Yeah, late reply here.

If ENUM were viable, this concept already exists for the most part, 
at least in draft form:

  http://www.ietf.org/internet-drafts/draft-ietf-enum-cnam-05.txt

However, I don't believe for a second (though I did years ago) that 
ENUM will ever leave the control of the carriers, as you also 
insinuate.  I'm singing to the choir, though, since you already have 
a Freenum/ISN dialing method (http://www.freenum.org/) for your 
organization, Brad.  Encouragingly, the ISN dialing method does scale 
quite well for the CNAM-type data to be put in the DNS with the CNAM 
extension draft referenced above, unlike E.164 which is more 
cumbersome, to say the least.

In other news:  I'm looking for an inexpensive CNAM provider via 
HTTP.  Low volume at first, but probably ramping up a bit over time 
to a few thousand lookups a day.  Anyone out there providing this 
service with a "low friction" business model?
