I think this misses the point for getting software into congress - it has to be something they want to use, not just something we want them to use. These are awesome ideas, but once we get into the "force your legislature to start using..." then it's pretty much dead in the water. We need to make software that makes parts of their jobs 10x better, and unfortunately that'll have to include a few ways for politicians to obfuscate and make decisions behind closed doors.
