Using the shell service and pty's, you can now create a simple SSH terminal client. (You'll also want to download and install the "ruby-termios":http://arika.org/ruby/termios library so that your input is not interpreted in a linewise fashion.)

The above code is also available as an example script in the Net::SSH distribution (@examples/ssh-client.rb@).
