I think the solution to this is for the industry to add a set of licensed frequencies to the 802.11 spec. They could set it up so that base station operators would rent the alternate frequencies for their events (either baked into the cost of the AP, or on a time/geographic limitation basis), and consumer client-side devices would of course need to be updated to implement this additional spectrum when talking to a licensed AP. Of course this doesn't do any good for existing consumer devices, it would have to be baked into the next 802.11x spec.
