A simpler proxy solution than the one Arnt suggested might
help.

Set up a proxy at the remote site and do small syncs during off
hours to keep the cache warm.  Syncs done from the remote
site will get their fil contents from the proxy.  The proxy will
hit the main server to retrieve metadata.  This can greatly
reduce the bandwidth demands for syncs, especially if the
files are large and if many users request the same files.
