No, David, the non-tech word for application is "program". This list is
proof - people here hear "Microsoft Database application" and they assume it
means "Microsoft Access".

Maybe you should read it yourself, David - it includes a very good
description of what the Jet engine is, and a description of an exploit that
has very little relevance to the situtaion we're dealing with (why would you
need an exploit if you had physical access to run your own code on the count

Again, David, why would you need a buffer overflow if you had access to the
system? If you think custom code from PowerVote/Nedap for burning the
results to CD would be immune to buffer overflows, I have a bridge that I'd
like to sell you.
