I'm also thinking that Level 1 and 2 universes may not be infinite in
extent which limits the possible observer moments I have access to. I
have argued before on the list that the question of topology of the
"universe" is far from clear. Those OM available from level 3 are
possibly more directly accessible ( if MWI is true in the right form).
