Hi Dave, in my role as IETF TSV AD, I would be happy to help
you get this into the IETF.  Please note that you can't get
a Standards Track RFC published without a working group
adopting it or an AD sponsoring it.

This topic would be of interest for the IPPM and BMWG working
groups, and I know it is of interest to me as a TSV AD, so we
should be able to find a way to bring it in.

In fact, the timing is good, as FCC folks are at the IETF this
week talking about their vision for broadband test and
measurement architecture, and these tests may relate nicely
to that proposed work.
