How would the key fingerprints not match?  Fingerprint the key once,
fingerprint it again, I'd expect ~every implementation to get the same
fingerprint each time.  Indeed, for fingerprints to be useful it would
have to.

If you're trying to fingerprint it and then fingerprint the similar key
which is identical except that it calls itself ssh-rsa, yes, the
fingerprints should differ.  But I suspect the latter key "doesn't
exist", certainly is never sent by anyone to anyone, meaning there'd be
no difference to notice.

If it's accessible at a globally-routed IP you can point me to, I could
try to connect to it to see what moussh does....
