Obviously, although I'm sure many people would like a couple of
hundred MB/sec over their network :-)

I meant ssh with public key. I'm interested as to how cfengine's key
system is "better" then ssh's.

Well, standard rsync server is relatively "insecure", is it not. No
public key, no hijacking checking (if that is the correct term for
it). I was under the impression that ssh is recommended because it is
relatively secure if used "properly".
