Hi Tom:

This may be no solace, but it just works for me out of the box.
The one exception is that graphics don't pop open, but I can
live with that.  So, I just remotely tramp a file.  Then, in
that buffer do a M-x R  For me, that opens a remote R session;
no ssh.el required.  C-c C-b submits my remote file to the remote
R.  ESS is amazing!
