The Austin Chronicle has a fairly lengthy piece on e-voting in general and Hart’s machines in particular. If the article is presenting the situation accurately (and I have no reason to doubt that it is) then it looks like Hart InterCivic may be one of the good guys.
There’s some good stuff about e-voting machine design in this piece; it’s well worth the read.
