Oh I know they are. I was doing all of this stuff while in grad school back in 1996, and later at my first job I was doing this stuff too. Had to use LynxOS back then. Would have been nice if we could have used Linux... I was watching RTLinux closely back then -- long before the patent problem. :)

That was the hope. So people would understand that this isn't the type of application where you can just squirrel away the real-time bits in a device driver... Its got to be the whole thing,
