Can the surfaces be substituted by planes? That will really speed up the intersect, but since you have 1400 surfaces, i doubt you can substitute them (planes have no boundary).

If it's total, that's pretty much real- time. I remember playing Quake II with 200 msec ping (latency) before broadband and i was able to deliver a fair amount of damage, of course it required some really good predictions skills since you had to aim where the other guy was going to be, not where he was.
