Re: vendors vowing to cooperate with disclosure?

If federal legislation offered NO COTS exemption but rather required full
source code disclosure, would there be voting equipment available for
purchase for the 2008 elections, and if so, what would it look like, cost,
etc?

I am looking for a practical answer on the IMPLEMENTABILITY of a full
disclosure requirement.
