yup.   i think we've done OK on that score.  i haven't seen any proposed
spec changes that were motivated by hardware improvements (or anachronisms).

interesting, great idea Dave!  got proposal?  for starters we just need
a node signature to define fields and some simple explanatory prose on
how it works.  an little chunk of example scene would also be helpful.

FYI there was a way cool demo at the W3C Tech Plenary TPAC meeting
by the head of the Cascading Style Sheets (CSS) group + "CSS Strike Force."
He moved his laptop around to drive a car game as a web application.
Apparently they were able to reach all the way down from the web browser
to the hardware, where there was no special configuration but rather
simply reading an accelerometer that already comes with the hard disk
(to prevent crashes when moving around).  so we should expect that the
accelerometer information will be widely available on almost every
platform, not just mobile devices.
