Personally I'd favour individual, private listening booths at concerts instead of rows of seats. Between events they could serve as dining rooms, overnight sleeping cabins and commodes, thus easing many of the traditional festival pinch-points.

Still, congratulations to the Blitherscrum committee for the progress made to date and for your on-trend-Coalition-style-consulting-the-punter-policy-making-model.
My only quibble is that you haven't yet got enough rules. You could overcome this by taking on hundreds of stewards who can then make up the rules as they go along. Bingo!
