Of course, next-generation vertex shaders target the
same ecological niche. But affordable gaming hardware accelerating
physical simulations is distinctly Good News.

Unrelatedly, OpenCroquet allows remote synchronization of distributed
simulation instances. It's based on Squeak (SmallTalk), but can in 
theory allocate masters (which might be accelerated, or have hardware
entropy) replicating world state to slaves. (Of course, if the world
state is rich, the replication incurs high costs, especially if over WAN).
