I would love to see this carried out.  I have no idea what the results would be, but I'm always interested when an intellectual puts his money where his mouth is.

The only immediate flaw I can see in his proposal is that there may be some way to use coded words or themes as a signal, although even that would be hard to coordinate.  Also, there would need to be a sort of simpler Turing Test for the readers in the proposed experiment in order to prove that they know what they're talking about.
