Rsync and ssh with passwordless authentifikation

I use ssh to tunnel the rsync ports but I think rsync ssh could use the
same technique. You have to start an ssh agent which contains the
passphrase in memory (and therefore is not on the disc anywhere). This
is very well described in O'Reilly SSH The Secure Shell "Snail" book 
pages 374/375.
