Imagine you extend the technology described in above link with cellphones capabilities.

Pick up 2 bluetooth enabled phones; mount them on a structure, side by side; add a lens system which allows looking at phones screens from short distance (2-3 inches); add a WII sensor.
Now write a PC program which sends images from PC to cellphones via bluetooth.

What you obtain is a virtual reality head up display!

Is it feasible?
Which is rhe maximum throughput allowed by bluetooth? Would it allow a 320x200x25fps streaming? Or, at least 176x208x15fps? (Without compression, a 256colors 176x208x15fps stream would require ~500,000 bytes/sec)

If streaming is not possible, anyway modern phones have enough power to show 3d graphic,so the computing could be made directly "onboard" of the head-up display!
