I see the essence of {mu'ei}, which serves to express English 
_would, could, maybe, if_, as involving possibilities -- whether 
you call them possible worlds or possible states of affairs is
a secondary matter, to be decided according to taste or to 
philosophical soundness.

It's in one or more places in the wiki maze. The idea is that just
as mu'ei quantifies across possible worlds that are relevantly
similar to the local world, so ba'oi quantifies over possible
futures -- i.e. over possible relevantly similar worlds whose pasts
are identical to the past of the local world. Again, if "world" is
a bothersome notion, please recast the formulation as you think
fit.
