I haven't hit a case in years where the encryption overhead was actually
measurable as a significant issue.  Still, anything you can do over ssh
can be done just as well over rsh.  There's always rcp if you want the
same syntax as scp, but if the data consists of a lot of different
files, using tar on both ends of a pipe will probably be much faster.
