 	Yes, I'm already doing this, but I like to have a passphrase on my 
dsa_key... For my normal login, I run the ssh-agent and supply the 
passphrase at every login (only once a week or so).  That key.pub is 
distributed to all the machines I log into, but is only stored unencrypted 
in memory after I supply the passphrase.  I would like an automated backup 
to connect to that agent and use the key that's passphrase-protected.

 	Hope that makes sense.  It's quite possible that what I'm trying 
to do is stupid and I'd realize it if I thought all the way through it. 
All I know is if I type 'backup_script" logged in normally, I've got my 
passphrase-protected key exchange that doesn't require a password.  If I 
put it in a script, notsomuch.
