Re: [netmod] I-D Action: draft-chopps-netmod-geo-location-00.txt

This is a neat draft.   Reminds me of when I worked on the Virtual Reality and
real-time simulations.    I once wrote a class to convert locations, vectors, and
orientations to and from WGS84 geocentric coordinate space and topocentric
coordinate space systems.   I was fresh out of college with a Math degree, so
of course they gave it to the new guy (me) to figure out  ;)

Anyway, while WGS84 appears to still be applicable, it looks like a lot of other
standards work has occurred since.   I'd have to dig into it to provide a deeper
comment.   From a gap-perspective, it seems that this module covers locations,
but not vectors or orientations (intentional?) Note: "heading" defines a value in
just a single dimension, so doesn't work for VR.   From an add-perspective, I'm
surprised to see "speed" included here, at least we always had 1st (and 2nd)
order temporal information defined elsewhere.
