The connection with string or M theory strikes me as tenuous. Re-entrant wormholes at the particle level, maybe - but that's within a single universe.

As for the budded cosmoses - Smolin's is a nice current version, and David Deutsch told me that his QT multiverse theory (the Cat is definitely both alive and dead) is not inconsistent with Smolin's, although they seem disjunct on an analytical level - both might be true, or one, or neither.
