Re: PTTH (aka Reverse HTTP) BoF in Madrid

Hi Michael,

The PTTH BoF went well. There was interest from the community to work on
this problem, and enough folks indicated that they were interested in
writing or reviewing drafts in this space. If you're interested in more
details, the minutes are at [1] and the video at [2]. In terms of next
steps, a PTTH email list has been created [3]. We will be coordinating
there, and the proponents will start work on a potential charter.

Thanks,
David
