open source schemes might offer similar features, and perhaps overcome
some of DNS's security issues as well.  Discussing naming service

ADSP has stipulated DNS and its heuristics.  ADSP should declare the
extent of the policy and stipulate this policy _only_ relates to email-
addresses suitable for SMTP and DNS.

DNS yes, but why SMTP? SMTP is not the problem. It is DNS that is  
(possibly) a problem. DKIM already relies on DNS, so I see no reason why  
ADSP should differ.

It would be utterly stupid if someone invented a naming space with the  
same syntax as domain names but using something other than DNS, and then  
let those names wander around freely on the internet. At the very least,  
any such scheme MUST use some TLD(s) distinct from any that is approved  
for DNS usage by ICANN.
