I usually lurk as well, but wanted to respond to your question.
There's so much debate for one simple reason. All the known solutions have been ignored. This is why everyone is getting so upset on this issue. Companies like Diebold have ignored all the previous work on this subject, work done by people like Bruce Schneier. They've ignored all the problems with their system, up to and including their complete lack of verifiability. They're already, in a rather short history in this field, shown a complete lack of accountability (think the various unapproved revisions that got them sued in California). That they've been so determined to weasel around the _known_ solutions to these issues casts a great deal of suspicion on them. Their continued resistance to even the simplest fixes, combined with their repeated denials of any problems, is only making things worse.
Unfortunately, I don't see any major changes to this happening until some state's electoral votes go to CowboyNeal or Bill the Cat...
