	How about having a rasterizer feature in hardware that can draw
lines instead of pixels?  Give it a motion vector for each object you're
drawing, and instead of rasterizing pixels, it will rasterize lines passing
through the actual pixel in screenspace, fading in alpha with distance from
the actual pixel location.

	This would make an excellent simulation of light reflection caught
on film from an object moving quickly in a straight line, though it wouldn't
look very good for spinning cubes and such.  I suppose you could provide a
velocity vector per vertex and interpolate the blur vectors on a per-pixel
basis.  With blazing fill-rate I think this could become feasible, and look
quite nice.

	Any IHV's up to the challenge? ;)
