scp. Without a doubt.

#!/usr/local/bin/python

import os

host = raw_input("Enter a hostname: ");

os.spawnv(os.P_WAIT, '/usr/bin/scp', ('-v', 'username@%s:/home/username/TESTFILE' % host, '/tmp/TESTFILE'))

os.system("pico /tmp/TESTFILE")

os.spawnv(os.P_WAIT, '/usr/local/bin/rsync', ('rsync', '-v', '-p', '-e', 'ssh', '/tmp/TESTFILE', 'username@%s:/home/username/TESTFILE' % host))

This will fetch a file with scp from a remote host over to the localhost,
then rsync it back after a change was made with pico. But your only
interested in the scp line. Works great, even with RSA keys.
