Description
Currently, dbcast broadcasts a single file. Some people want to broadcast entire directories.
A work around is to tar up a directory, bcast the tar file, and then untar in parallel. That works, but it's ugly.
We could walk the directory, and then we'd need the writer rank on each node to recreate the directory structure, from top down. We then need to handle reading and writing files in parallel (efficiently).
