[Dirvish] Is this a dumb idea? rsync without ssh

[Petcher, Daniel]

I'm working on moving my dirvish server onto some new equipment and
re-organizing the archive, so I've got a few TB of data to move. When I
rsync from the old server to the new server, the data goes over a SSH
conduit. I'd like to move the data faster since I know it's entirely
contained within my trusted network. How do I turn-off the ssh encryption
tunnel?
