great - we are happy to get comments

It is a trade of between public SIP URIs and private peering factories. 
Currently peering between SIP providers happens in 3 scenarios:
- open SIP URIs (like iptel.org, fwd ...): this wont be used by big carriers
- TDM interconnect: that's the worst solution, but currently the most used
- private peering fabrics (xconnect, ...)

Currently, ITSPs which do want to peer via SIP but do not want public 
SIP URIs because they want some kind of security/authenication/control 
have to use private fabrics (operated by 3rd parties).

Our idea helps by putting federation membership into public DNS, whereas 
ingress points can be public or private. And no need for 3rd party 
peering fabrics.

Honestly I would be very happy if I can put this module into the thrash 
because carriers start using open SIP URIs.

carriers won't use public URIs in the next year. I am worried too.

That's the advantage of VoIP peering - there is a backup route via the PSTN.

Regarding Email: Here the main problem (also like in SIP) is 
authentication. That's wy I'm eagerly waiting for domainkeys.
