Sun Shared Shell
Sometimes, you find some features and services of Sun by mere chance: Sun Shared Shell. Sounds really cool. A collaborative shell. Really helpful when you need to support a system at a customer site. And even more interesting: This is really a shell to to work collectively on a system with multiple user level (execute, non-execute (you can´t submit a carriage return) and view-only), you can draw on the window and you have a chat to communicate). A really nifty tool.
