I'd like to add a method, but I'm unsure where to start.

The method would allow you to login to the machine as one user and
then use su to go to another user that was not allowed to log in.
There are various examples of this, but in my case, I'd like to edit
files that only root can touch on the machine, but root is not allowed
to do remote logins.

I figure that rcp.el should be able to do this from everything else it
is capable of.  The only problem I see is telling it which user to su
to.  I can get around that in the short term by assuming that you want
to log in to the remote host as the same user that you are logged in
as on the local host.

My question:  Where to I start to look for stuff to change?  I'll need
an su in there somewhere and perhaps a second prompt for the password.

Ideas?
