Yes, we can use popen() with ssh.

Many people don't realize that the 'ssh' command can be used like 'rsh',
so we can do something like this:

>>> import os
>>> my_bash_profile = os.popen('ssh aztec ls -l .bash_profile').read()
>>> my_bash_profile
'-rw-r--r--    1 dyoo     users         354 Aug 23 12:04 .bash_profile\n

Hope this helps!
