Sorry for delay...
I'm not sure we did discuss events wrt ordinates. No reason that the same approach couldn't be taken (rather than just the look of something being determined by an N dimensional ordinate but also its interactive behaviour).

Aside from that, a solid abstract model of event sources (tying into the "real" world, along with interaction method discovery/capabilities)  would be a good foundation.
