Err, no. rdist and rsync and rdump all require an rsh-style channel.
The point I am trying to make is that:

	.	rsh cannot be configured to provide a channel for these
		tools without providing login access, which is
	.	ssh cannot be configured to provide a channel without
		high encryption overhead, which is undesirable.

netcat can solve this problem. I'm not sure what other tools can
(other than gssftp, with "PROT CLEAR").
