I'm a little more cynical and, as much as I love the idea of a truly open and progressive coalition government, it strikes me as being window dressing more than anything. Not least, as you say, there is no clear path to implementation.
I can't see them repealing the Human Rights Act, for example, even if 99.9% of the 'ideas' put forward were demanding exactly that. The concept, as conceived here, seems fatally flawed.
