You've met a lot of them at M3AAWG.  Also see draft-ietf-dnsop-isp-ip6rdns

I hope we are not so foolish as to repeat the NAT fiasco and stick our 
fingers in our ears becuse the rest of the world doesn't work in a way 
some of us might prefer.

The reality is that if you want people to accept your v6 mail, your mail 
hosts need rDNS, and not rDNS that looks like it was autogenerated by 
kludges like BULK.
