Projector based HMD?

I just posted in the user news and announcement forum about the Vivitek Qumi mini projector with 3D capabilities and WXGA resolution.

I don't think we have directly discussed the idea of using a mini projector in a HMD. I imagine such a thing might look something like an oversized motorcycle helmet. Here are some links to a Toshiba version of this idea;

I imagine that using the projector I listed would require that the projection be reflected off a spherical mirror to make it wide enough to cover a large field of view for the small distance it would have to travel. The only other option would be a different projection lens.
The weight could be reduced if it doesn't try to isolate the user from the environment by totally enclosing the head. I.e. require that the user be in a totally dark room to prevent washing out the image.
