[rssac-caucus] possible new work item

[Davey Song]

Hi Joe,   it's an interesting work item.  Similarly,you may notice Paul,
Kato and I initiate Yeti DNS project (http://yeti-dns.org/) which is
dedicated to the scientific and study on Root system. I think it is good
place to do some experiment and study on your proposed Item in Yeti
testbed.

Personally, I'm happy to join and discuss how to create the work party.

Cheers,
Davey
