Thanks for the reference - but I had a problem with it. It shut down my
Internet Explorer for some reason. I found this article, which may be the

Quantum spacetime: what do we know?
Authors: Carlo Rovelli
Comments: To appear on: "Physics Meets Philosophy at the Planck scale", C
Callender N Hugget eds, Cambridge University Press
This is a contribution to a book on quantum gravity and philosophy. I
discuss nature and origin of the problem of quantum gravity. I examine the
knowledge that may guide us in addressing this problem, and the reliability
of such knowledge. In particular, I discuss the subtle modification of the
notions of space and time engendered by general relativity, and how these
might merge into quantum theory. I also present some reflections on
methodological questions, and on some general issues in philosophy of
science which are are raised by, or a relevant for, the research on quantum
gravity.

This scenario that you are discussing reminds me of this interview with
Julian Barbour where he proposes that "time" is an illusion.
This reminds me of a good paper by Carlo Rovelli (about quantum gravity, GR,
space-time, etc.)
http://ws5.com/copy/time2.pdf in which he suggests that
the temporal aspects of our world have a statistical (thermodynamical)
origin, rather than dynamical. Time is our incomplete knoweldge of (the
state of) the world.
Not sure, though, whether the motto "Time is ignorance" can solve the
question, by SPK, about the quantum, or indeterministic, "block universe".
