"Corruption -> While a vote can be virtual his ballot should never be. A voters vote would print out at their normal polling place where a voter could go pick it up and review it before it is scanned into the system (or change it). Or, a voter could elect to encrypt his pin number into a bar code on the ballot that would allow poll workers to automatically submit the ballot for him."
The crux of the problem, IMHO, is that whether electronic or not, you cannot remove the human being screw-up factor (on purpose or by accident), from the election process. Whenever you get humans involved, things get messy...puny humans.
As far as library cards are concerned, what is to stop me from breaking into the Library's system and altering data (such as making all registered Republicans "deceased")?
I am super interested in your thoughts on implementing this system, can you go into more detail?
