I generally try to avoid using raw paramiko.  Fabric gives you a much 
nicer interface to the same basic functionality (and is indeed layered 
on top of paramiko).  The above functionality can be expressed in fabric 
as simply as:


---------------------------------------------
from fabric.api import env, run

env.host_string = "my-remote-hostname"
run("rm -f /tmp/roy-temp")
---------------------------------------------

Of course, I cheated a little bit.  I'm assuming you have ssh access to 
your remote host; the above code depends on that.  Going through sftp 
makes everything more difficult.  You can drive sftp through fabric, but 
it's a lot more painful.  I also assume that you can use ssh key 
authentication, which simplifies everything compared to passing 
usernames and passwords around.
