I found out one more thing. iGet is hard coded to the default filename id_rsa for the private key. Save that with no passphrase in your .ssh folder and iGet will recognize the key and use it. Nothing else I could do worked. Even changing the name to iGet from id_rsa so I could recognize the key as being the unsecured key for iGet would not work. These guys really ought to take a page from Cyberduck.
