I went to the AUSGRAPH trade show this week in Melbourne, and Silicon
Graphics had a 3-D setup running with wireless glasses.
The glasses were synchronized with an IR transmitter mounted on the
top of the monitor, and were completely separate (i.e. had batteries
built-in).
It was running off a Personal Iris with a special 3-D adaptor. Basically
you draw the left picture in the top half of the screen, the right in
the bottom, and the hardware does the rest.
The demo I saw was an X-29 fighter fully rendered in real time. It
was really impressive when it flew straight at you.

The cost - $3600 (Australian dollars) on top of the cost of an Iris.
Probably ~$2500 in the US.

So the hardware DOES exist. All you need is the software.
