[vos-d] Physics Braindump

[Ken Taylor]

For some reason I got physics on the brain this week, so I kinda went crazy
and added a bunch of thoughts to
http://interreality.org/cgi-bin/moinwiki/moin.cgi/PhysicsInVos ... mostly
about client-side prediction, intended-movement representation, and using
access control permissions to enforce a sector physics simulation.  I'm no
physics simulation expert by any means, and I still have a lot to learn
about VOS, but I got a good picture in my head of how VOS physics could work
themselves out. I was inspired by http://www.gaffer.org/game-physics/
(especially the article on network physics) and
http://developer.valvesoftware.com/wiki/Lag_Compensation ... feel free to
comment/criticize/refactor/ignore :)
