I agree. Quite a few of the cluster programs I know - including some I've written - use PVM/MPI for scatter/gather where I would now advocate to do it via a web request. One of my clients did that, but one problem was they didn't have any in-house experience for doing scalable web services, while they did for MPI.
The MD codes I know of use spatial decomposition where each cell communicates with up to 26 neighboring cells and where the data exchanged is very uniform and consistent and where communications is a non-trivial part of the overall time, which is why I think fine grained communications is still appropriate there.
