The misanthropic universe seems to be like that, with domains
separated by *vast* distances - not just cosmic bubbles from
inflation, but also the distances induced by accelerating
expansion during the vast periods of heat death. It is an awfully
huge place, even for an universe.

I think the model would allow this, since it is based on inflation
occuring. Hence the "simple" way is just to wait until a random
fluctuation happens (ignoring horizons) and modify the symmetry
breaking. Piece of cake, but takes exp(10^100) time... "Everyday"
induction of inflation ought to be possible and could create
custom domains in the model, but I guess they would have measure
very close to zero.
Unless they were very likely to cause the expansion of more
domains like that... hey! Quite possibly a good way out of the
conundrum of the essay is that such cascades of baby universes are
very common, manageing to crowd out the natural expansion-creation
cycle that makes most domains miraculous. If the likeliehood of an
inhabited domain inducing inflation was higher than the
spontaneous fluctuations and the resulting domain also shared this
property, then these would rapidly come to dominate the set of
worlds. And that would make most worlds non-miraculous!
Anybody feeling for writing a paper analysing this?
