'Open source' politics

I had a conversation with a friend last night about the way open source works as an effective way to develop public software. Somehow the conversation turned to politics and it made me wonder: Is it possible to use open source methodology in polticy making (theoretically at least) so that policy is produced and reviewed publicly. Is it be possible to make policy reviews on a 'what works best' basis rather than 'what do most people think is best' basis?

Discuss.

open source politics would fit well with the " many anarchy's" model

an ever changing network of polities all experimenting , collaborating, and competing to see which governance is most free and most efficient
