What is the contents of 'mykey'?  Is it a file object? A string containing
the contents of ~/.ssh/id_rsa? The Paramiko docs indicate mykey should be a
subclass of PKey, probably RSAKey.

So, you'd need to do:

mykey = RSAKey.from_private_key_file('/path/to/private/key/id_rsa')
transport.connect(username = username, pkey = mykey)

Beyond that, I"m not sure.  Of course, I've never used Paramiko before.
