You may find this ping-worthy.
His argument is total BS. Read carefully what MS is proposing. They are saying that if someone builds a voter app to run in their environment that MS doesn't have to release the environment to the government or anyone else for independant review. This would remove the ability for pretty much anyone to get a look at MS's operating system source codes.
IE - if you build a voting machine app using pocket PC software, you still have to release the code - which anyone who knows software can reconstitute on a pocket PC environment and verify it works as it is suppose to.
The developer of the voting machine equipment themselves don't even have access to the environment source. MS is just doing this so that people can use their awesome development tools/environment and compete with those who are not.
