But you would have to run the computation, to compute the sequence
of trajectory frames before you can start reshuffling anything.

No problem, as long you have a last state to resume from, which 
continues the trajectory.

How can you compute things out of sequence? The nearest analogon is
hash Life (building a hash table of recursive light cones, using the 
fact that conformation distribution is very far from random, which
allows very large speedups, at least on older sequential), and I'm 
not at all sure what this cause to in-world embedded observers (Life 
is an all-purpose computer).

If you're a process, and you do some fancy nonlinear things in
the trajectory computation, even though the target state is the same,
I'm not buying the first-person observation is ok.
