There actually is a patch to provide encryption "none" to improve speed and 
reduce CPU for trusted connections.

HINT: sure would be a nice addition to Fedora FC14!!

It's really desirable for doing scp or ssh to/from a VM from the host. Why spend 
CPU encrypting a connection which is as trusted as possible? Note that for just 
file transfer netcat can be useful if you have the firewall set to allow it.
