I must say that I don't believe in tantalizing the customer. I don't
believe in vaporware or the tooth fairy either. Also, the best "legal
protection" for patentable equipment is to keep your mouth shut.
So right now, the readers of sci.virtual-worlds have to put up with
Mr Frerichs' almost weekly content-free updates. So my question is, if
you have nothing to say Mr Frerichs, why do you keep saying it?

Besides, legal protrection from what?

Very nice, but unsubstantial. What are the I/O devices? Powerglove? knobs?
3D joysticks? projection TV? Homebrew head-mounted display? Any 3D trackers
involved? How do they work? etc....

Static polygonal objects downloaded into an execution machine. Manipulation
restricted to position and location of objects. Otherwise, why do you need
C libraries and the download procedure?

This is more or less the definition of a video game.

So what? You can get that with Flight Simulator on the PC!
Maybe you're easily impressed!

Well, it SOUNDS like you're being coy for no good reason.

First off, I wouldn't be so hasty about accepting the "fact" of subjectivity.
However, this criterion of "replacement" is too loose. A Walkman creates
a virtual reality, but you wouldn't normally think of listening to ocean
waves on a hypnosis tape as "Real VR".
