I believe the fundamental question revolves around beam (or "energy") density. If you make the beams energy dense enough (from not say two continuous beams, but 256 beams with femtosecond pulses on the same production/collision schedule), then you have a fundamentally different kind of experiment. Simple beams pass through each other with little or no effect. The question is, when does the energy density become high enough to effect that the "fabric" of space/time/energy/mass enough to effect the progagation?
I believe some of the messages have addressed some of the limits, but I don't believe we have closure yet.
