I'm personally fine with a discussion here of whether an interoperable standard is worth the effort, likely to be adopted, etc. 

Previous versions of this discussion have included use cases where interoperability is part of the value of an alias feature-- for example, if I'm a domain owner who wants both to determine the behavior of an "alias" in terms of what a client sees and to have flexibility across managed-DNS providers, I want a standard to hold my vendors to.

As a first cut, the general topic is IMO on charter for the WG, if people seriously want to work on this.

I like David's idea of an informal BOF. I'm not sure of logistical constraints for the venue in Honolulu but I'm happy to work on pulling something together. 

Descriptions of the workings of the known "alias" features currently in the world would be helpful inputs, along with any specific use cases or problem statements people have in mind. The goal would be to get a preliminary idea of whether there's useful work to be done on the subject within the IETF process, beyond periodic bull sessions on the list, and if so, what's the most effective way to proceed.
