M2dude,
It's the answer I would have given, but without your know-how and background.
Also, the near-monopoly, with only a hundred seats on offer a day, would probably have assured enough customers for whom time was indeed money, and for whom being able to 'pop over' to NY and back the same day, in person, wold far outweigh 'video conferencing'.
If I said 'near-monopoly', it was because 'straight-out' / 'straight-back-in' business jets are already aiming to provide a similar (if not the same) service, with the added advantage, compared to LHR-JFK-LHR, of being capable of providing more "door-to-door".
I suspect that, if a SSBJ didn't need so much "back from the ground up" engineering, one would already be flying.
