Paid people at polling stations?! Be still my heart! My father's unpaid, and all his people are volunteers and completely uncompensated (at least in Maryland), and the hours they pull and the shit they put up with... And finding enough folks to cover the jobs is a challenge.

But that single roll and ability to access it from multiple points would be top notch ways to prevent voter disenfranchisement (provided the voter can travel, which is usually not the case), or account for disasters like Sandy. Right now, that's a major problem for a good chunk of the local elections on the eastern seaboard.
