What to do about GPUs? (and the built distributions that support them)

The wheel selector suggestion was intended to make the process automatic much like the the prior selector package idea that it references. It was pointed out though that in many situations there is a need for users to control the selection.

Just having variant wheels and an explicit way to select between them sort of seems like a prerequisite to designing anything that would give automatic wheel selection so discussion moved off in that direction. I think it is very much the case though that there needs to be a way to handle this automatically for most users.
