Nope.  Password only exist in memory locally.

If you want to see the whole program in action as it currently exists:

   http://www.tundraware.com/Software/tsshbatch

I do a lot of work in very large data centers where I need to execute a
bunch of commands across, say, a thousand servers.  tsshbatch has solved
the problem neatly for some years.  I'm just trying to knock some of
the rough edges off it :)

P.S. There are other such programs like 'capistrano' that are spiritually quite
      similar.  I wrote tsshbatch before I found out about the others, which
      are all written in other lanugages (like Ruby).  So, not only did
      this serve to solve my problem, it also taught me paramiko :)
