	One caveat is that, in order to use the RSA key for authentication,
you've essentially got to ssh from client to server, then from server to
client. That way, both of the machines are present in your "known_hosts" 
files. Thus, something like....

	localbox$ ssh remote.box
	Enter Normal password:
	remote$ ssh local.box
	Enter Normal Password:
	localbox$exit
	remote$ scp local.box:identity.pub .
	remote$ cat ./identity.pub >> ~/.ssh/authorized_keys
	remote$ exit
	localbox$ ssh remote.box
	Enter RSA password:


	... And you should be good to go. The trick is that, from the remote
box, you've got to ssh back to your local box in order for the remote box to
get an entry in it's "known hosts" file.

	Take a look at sshd(8). Read up on the "RSAAuthentication" option. By
default, ssh enables RSA authentication over rhost authentication, so, chances
are, if you *want* to use RSA authentication, you won't need to make any
changes to your /etc/sshd_config.
