These both are technical issues. The first one - maybe there is no need for a director, when you can have multiple versions of a scene - which then can be voted on. The second - the system would have to ensure that that hack would only get paid proportionally for contributing the farts.
I know it all sounds crazy, but I'd be wary of underestimating the power of community. There may not be processes to convey such group endeavor yet, but then these are a matter of discovery - also a group effort.
