Brian, that was a great meeting; thanks for setting it up.
I put some quick meeting notes here:
And I wonder if there are existing physics-tool development lists worth
pinging for a future meeting. They could provide their own speed and
compatibility tests... and I'd like to hear what people like the linerider
devs think about XO variants. (that's much less than full mechanics, but it
does rely on a gravity engine and touch on what's a good extensible
interchange format for scene design)
