If the Sun is hacked, an attacker can (potentially) see every password 
you type.

You almost certainly want two passwords, first for the ssh connection 
and second for the gpg.

What I've seen other people do is use two keys one for home and one for 
work/school. It seems to work pretty well, you can sign them with each 
other and take both to keysegning parties.
