Easy to use is good. Did you survey Boost.MPI?

Marshalling and unmarshalling data structures is a real pain. On the
other hand isn't it something that has to be explicit when working with
MPI since the MPI API works solely in machine level data types.

I don't have any D-related material, and I don't use MPI for big
cluster-based codes, but I use MPI a lot for some small algorithm
benchmarks. So if you need someone to bounce idea off, feel free to
include me in the set of people you drop a line to.
