Re: [media-types] [art] [dispatch] Status of Haptics I-D in DISPATCH?

["Murray S. Kucherawy" <[e-mail]>]

Hi all,

Thanks for this discussion.  At a minimum, it reaffirms my decision not to
sponsor this myself.  :-)

Francesca and I talked about it this morning after the IESG call, and
decided that I'll take up the pen to write a draft charter based on this
thread and circulate it for comments.  Stay tuned.
