That's true, but how practical is it to verify an SSH fingerprint? All
you have to do is log in and check the host key. Oh, wait... With SSL
certs, at you have a CA infrastructure for verification (which often
doesn't get used). Around here it's enough if I can get people to use
SSH instead of telnet. Asking them to verify against a list of SSH
fingerprints would go over like a lead balloon.
