Re: [dnssd] New Version Notification for draft-huitema-dnssd-privacy-01.txt

[Tim Chown <[e-mail]>]

Hi,

Ralph and I would like to encourage some review of this updated document, particularly as it is now stepping into a proposed solution space.  

Privacy aspects are very important in all our work, and it would be great to have feedback on the updated draft in advance of the meeting in Berlin.

Many thanks,
Tim

Daniel is completing his PhD at the University of Konstanz, in Germany, studying issues related to privacy and discovery. This new draft is in my opinion much improved from the version 00 that I presented in Buenos Aires. You can read the abstract below for the broad lines of the proposed solution. Or, better yet, read the draft and comment!
