Cool! Very clever that CSS guy. After I wrote this I realized that such
things would be likely,
that external code could drive SAI, and that external code could
Keith Victor has been doing some thinking on a node for it. I would bet
that BM and Fraunhofer
have too, not really sure. I can draft up something if nobody else has,
would like others' input
While we are at it, access to the hardware compass and GPS would also be
very nice. Again, probably
could be driven externally, but having them handy is also, well, handy.
