I agree to Richard. imho the ENUM thing is already complicated enough
(not the DNS stuff itself, but the administrative challenges of keeping
DNS and E.164 space aligned). 

Adding another "feature" would increase the complexity the trials, and
therefore increase the risk for trials to fail.

We hope to the trial to give us incredibly value of the first real
interaction between the internet and telephony domain. Isn't that
alone already a challenging mission?

Could we agree on "Securing ENUM DNS zones should be investigated during
the trials?". I think we are a bit leaving off the main path of the
document's pupose which are the "minimum requirements". Those are imho:

- Agreed topology in terms of DNS space mapping between numbering space
  and DNS (exists!)
- Client interaction between trial countries (tbd., depends upon
  standardization of NAPTR contents).
- Working demo applications to gather interest of both internet and
  telephony industries (in porgress)
- Administrative basics covered (processes in place for registration,
  changes, ceases, NAPTR modification)

Everything beyond that is imho nice to have for a _trial_. If securing
the ENUM DNS space is a must for production should be an outcome of the
trial.

No one from nllabs crying out?  nsd not an option?

I've already discussed that with richard: Naming vendors and versions is
not a good idea. One should name requirements. I'd suggest:

"Tier1 name server software must support DNAME if numbering plan
includes dial prefix shortcuts. Tier2 name servers must support NAPTR record 
type and. If ENUM DNS space is to be secured during trial, name servers
at both tier1 and tier2 must support secured DNS."
