I may have said this already, but we’ll discuss this at the dnssd WG session next Wednesday.  Our AD has explicitly said that privacy considerations are in scope (and should be in all WGs :) but we will need to have the conversation with the WG and the AD about the best place to proceed with the work, and about getting critical mass to ensure it completes (I’d assume Christian and Daniel would welcome all help…).

Best wishes,
Tim
