Anyone working on Collision Detection yet?

as the subject says, I'd just like to know wmat is the status
of work done on collision detection.
(basically I'm trying to start a new tmesad and hopefully
let the DEF one die piecefully :-)

It seems that there are many proposals on various behaviour
aspects, but not a lot of discussion on collision detection.
I don't know if some of you consider it a bahaviour as well
(not me though) but I think it is sometming that could be
achieved easier (in terms of specification tmat is) than
behaviours and I feel tmat it is equally important!
May only be feasible on fast machines (since we are talking
about computing power here and not graphics) but should be
possible to set a standard.

Any takers?
Any experimental, alpha, beta, gamma, delta (whatever)
browsers supporting that?

Cheers
