X11 is a standard windowing system used I'm not sure. But it could be added easily. >4. What will it cost in maintenance: hardware and software? Currently Again depending on your configuration. >Potentially, a 4 CPU version of the 4400 could be almost 10x the [Opinion Mode on] You didn't mention the OS you were getting (there are three UNIX versions commercial, realtime or C2 secure) so I don't know the application. Harris is very strong right now in real-time systems for data collection and simulation. The Nighthawk's context switch speed is among the best in the industry. If you have a real-time application Harris is your best choice. Otherwise, its a more difficult decision to make.
