Ouch. Yah, that makes sense. I guess I'm reading all the available keys 
even if the username/password is given... I guess I should make it not 
die if it can't load a key...

I'll fix my copy, but if you'd like yours to work just wrap a 
begin/rescue clause around line 196 of net/ssh.rb. That ought to do the 
trick.

Yah, I've tried various permutations of options with ssh-keygen and 
never managed to get a key with "parameter" values. That's why I'm dying 
for someone to show me how they generated their key, but everyone I've 
talked to that has one with the parameter values can't remember how they 
generated it! :) Ah, well.
