Yes, but only rarely is the "environment" an ideal gas or monolithic
solid such that our usual ideas of diffusion and dispersal will apply.
I suspect that we need to think about how decoherence works in a
framework that takes into consideration a wide variety of rates and
that considers how the phase entanglement is distributed. I have tried
to find work examining this and only recently some papers have come
out. See: http://www.quantiki.org/wiki/Decoherence-free_subspaces and
It took a while, but Tegmark's no-go is finally loosing its hold. (I
swear that guy is the reincarnation of Lord Kelvin!)
From what I can tell decoherence is more of an effects that
disperses among the many-worlds and not one that spreads within a
single world - like photons. We really do not have good physical
analogies for it!

Interesting idea! It reminds me of Sheldrake's Morphic fields. I
think that James P. Hogan wrote a novel based on a similar idea also,
except in "Paths to Otherwhere" the ideas was to "tune" in on
differing parallel worlds and even travel between them.
I think that we still do not fully understand the implications of
