For the kind of applications they suggest, the monitoring of various biological parameters, they could have them displayed as "meters" (my blood sugar is 3 bars ! yay the same as my cell phone) in the peripheral vision, that would still be readable I think; when you want to clearly see it you would "click" or whatever on a navigation device to bring it to the center of the field of view. Imagine your FOV surrounded by a ring of icons that you could bring to front using an ipod-like wheel !
When displaying something like a webpage I suppose you could use again a navigation device (trackpad/touchpad in the middle of the wheel ?) to center the interesting part of the document. I would suck for movies or pictures though.

In any case, the law was totally directed at Muslims. Did they make it illegal for a Catholic priest to wear his collar? For some reason I think not.
