Sorry to be part of the thread delay, but my problem with the whole consent-based resolution thing is that, as far as I am concerned, rules and mechanical resolutions exists (and exists in LARPs especially) when an agreement either cannot be reached, or an impartial arbiter (the random chance on dice rolls) needs to be invoked. If two players and their characters are in a proper conflict, then it should be obvious that at least sometimes, no agreement can be reached, because well, d'uh, its called conflict for a reason.

Even improv acting tends to have some guidelines apart from character...
