Why not parallel?  M worlds == M threads, with inter-world 
synchronization primitives.  Windows events look like a feasible model 
to use for synchronization primitives where you can wait for either any 
or all of N events to become signaled.  Or Erlang-like channels too.

How do you plan to move objects across worlds?
