    As a general principle, determinism is meta-physics.  I doubt that it can be
    strictly falsified because every possible test depends on auxiliary

    one might be willing to give up before declaring a general metaphysical 
principle
    was invalid.  But in the sense of having the preponderance of evidence 
against it,
    determinism has been falsified.  Quantum mechanics showed experimentally 
that no
    *local* deterministic theory can be right. So the principle of determinism 
conflicts
    with the principle of localism (no faster than light signaling).  
Determinism can be
    saved by introducing non-local theories, like Bohmian quantum mechanics or 
Everett's
    multiple worlds.


ISTM MWI is local but multi-valued, but local (no information travel faster than the speed of light).

I think it depends on the model of MWI. If you take Everett's original idea then a split due to a measurement "here", splits the wave function of the universe everywhere. Of course it's "local" in the Hilbert space where it's just a different projection. If you consider a decoherence model then the "split" propagates out from the "measurement" event. If you consider the multiverse model, then nothing physical propagates, you just learn which universe "you" are in (which was a non-local hidden variable).
