I'm a bit afraid of losing focus here. This started as a survey of systems
not properly serving AAAA RRs, then additional v6 considerations were added
and now EDNS0 is on the table. While all these are serious operational
issues, we might want to address them separately or point to and combine
efforts which already deal with them.
For example, there's work underway dealing with EDNS0 in the IETF and everyone
here will be invited to contribute.

For David's work there's the IPJ article including the reference to RFC 4074.
What else is needed? It might help to continue these surveys, but we'd need
to see what we're going to measure.

o There are some old or problematic implementations out there and it might
  be the vendors (for fixes) or the operators (for upgrades) or both that
  need to become aware.
  Do we want to identify these implementations (-> fingerprinting) or
  their distribution? Who's going to do that?

o Who's our target? End users/site administrators running name servers?
  ISPs? Registrars? Registries? {a possible recommendation _could_ be
  to include in DNS checks the correct server behaviour against AAAA queries}

o There's also the middlebox issue (both vendors and operators), which
  already bites us with EDNS0. Again, who is the target?
