well, like I said, it's not the simulation that needs to be distributed...
it's the calculations done in my custom command. I need to ba able in my
custom command to call some evaluations on different computers. For example,
the custom commands asks computer 1 to evaluate particles 0 to 99, computer
2 to evaluated particles 100 to 199... and then wait for the results before
writting them to the UserDataBlob and then going to the next frame. So it's
not the particle simulation per say but the custom command that the event
calls that needs to be distributed through the network.

An hour per frame....wow, you don't mess around do you :-) I didn't
think distributing particles was possible. I know that the Next Limit
guys are working on this I think but the obvious problem is that you
need the previous frame to simulate the next frame, etc.
