We're almost certainly not talking about MD-scale simulation here
(through the high watermark of a billion-atom simulation of Cu
crystals have been achieved, and I'm pretty confident that we can put
a cubic micron of a biological system into the machine, and look at 1
ns dynamics of it brute force (and much longer time spans with
tricks)) within the next decade.
In principle, if you could integrate these two current complementary
packages
http://www.nrcam.uchc.edu/
http://www.e-cell.org/
it would be probably up to the challenge of making a pretty good model
of a minimal organism.
