I wasn't able to find this functionality in rails to begin with, so I
wrote a small wrapper to allow you to provide direct IRB shell access
into any long running app (for debug purposes, or as a way to control a
remote machine).

In your app, just require irb/server.rb (http://pastie.caboo.se/58859),
then run irb/client.rb (http://pastie.caboo.se/58858), passing it the
DRb url.

This allows me to run an IRB window on my local machine, with access to
the currently running rails app on my server.

Hope you find it useful...
