I’ve thought of this of many times! But you’re missing the most important part: every reform should be a PR. With discussions and all. That would be the purest form of voting. And all decisions to reach the current state of a law would ve registered and available for everyone to read. Democracy 2.0.
This is already the case since parliamentary minutes are typically on the web as well. Unfortunately of course, this only includes the "official" discussions, not those taking part in corridors, offices, or lobbies... :)
Dreaming costs nothing.
