Has it been possible to build O-MPI for Windows (with perhaps reduced capabilities) to use ssh under Cygwin rather than WMI? We are only after a small subset of MPI functionality.

You should be able to build Open MPI on Windows either under cygwin or mingw to only support ssh. In this case, however, ompi will behave as it's Unix counterpart, and no support for any Windows specifics (such as registry) will be enabled.
