I just worked admissions for a festival in Seattle, and we have started seeing scalpers actually walk with the customer to the gate, and verify they get entrance. If the scalped ticket isn't valid, the scalper will refund right there. People have stopped trusting scalpers with print outs, because they often don't work. The resellers are realizing this and offering guarantee.

As an aside, many festivals and venues don't disallow re-entry due to TM implementation (I've been to enough TM ticketed events that have re-entry). They ban in-and-out so that you cannot go elsewhere to drink or eat without the festival surcharge and kickback.
