I was thinking that if one had an accomplice or two; and if one strategically placed one's accomplice(s) around the auditorium, each with a small and easily concealed speaker; and if one used a device capable of emulating 'surround sound'; one might be able to disrupt Mr. Romney's lies for quite a few minutes before agents of the 'powers that be' discovered the source of the "chittering"...
Not that I, of course, would personally condone, much less participate in, such a scheme, mind you...
I don't know if battery technology has progressed to the point where such a device could last the entire debate.
Good idea!
