I recognize the developer spirit here :D
Interesting idea, as endless meetings are a plague for many of us.
Aren't you afraid that people who can't restrain themselves during the first few uses will give up prematurely?
What's more, do you think there are enough open-minded managers out there to give it a try?
But on the other hand, it would force people to plan more effectively on their own. That's a very good thing :)
Good luck with the launch!
