But isn't the point of this discussion that if (and it's a whopping
great if) using the Hyperloop technology could give us inter-airport
transfers in the time it typically takes to change terminals in an
airport then that might change the dynamics and cost-benefit analysis of
where to put additional airport capacity in the overall London area.

But could hyperloop deliver this for airside transfers? Many passengers
at an international hub don't want a transfer that requires
immigration+baggage collection+customs followed by baggage
drop+security+emigration. Not impossible but segregating "airside"
passengers (and their through-booked baggage) securely on hyperloop
seems to me non-trivial.

Yes, that's a good point. As far as possible, air-side transfers are in a
single terminal, with automatic baggage transfers, and that's tedious
enough. If you had to arrive landside and make your way to the separate
Hyperloop terminal, with your luggage, that would be truly painful. Then
you'd have to do it all in reverse at the other airport.
