That's a surprise (to me at least). Foliations are just viewpoints, I
believe, and essentially arbitrary [added later - as you say below]. If you
summed all *possible* foliations, I'd expect you'd get space-time (assuming
the notion of summing them all makes sense...)

Or rather timeless? (Of course comp does that, with Platonia!) I agree this
is the sort of ontology we should look for, which is one reason I find comp
attractive even if I don't follow it all (but Bruno has promised to give

Yes indeed. Hence "relativity" ! But space-time itself is (within SR) is
preferred (so to speak). That is, there is one block universe, within SR,
in which (I believe) each point can be uniquely labelled.
