Hello Jan

You make me discover the new (?)
http://plato.stanford.edu/entries/qm-manyworlds/#7
It could help. Quite nice.

You can also search for Rubin, or Everett, locality, many worlds ...
in the Los Alamos archive http://arxiv.org/ (click on the "find" at
"quantum physics").
Many question remain, sure.
