Thanks for the responses, Michael and Brian.

So what I gather is that this would be doable if;
1) the communication between the grid and server is not significant
and 2) if the calculations could be secured.

These seem tractable issues for the most part, even for large simulations
a la Schulten etc. Perhaps even load balancing could be partially
parallelized and farmed out.

Security will always be a problem in large-scale distributed computing due
to systemic hacking, but small-scale? If the grid is geographically
localized to a managable facility, such as a university or company, then
security is enhanced by anonymity.
