I like their scenario of a projector that could dopy the entire contents of a hardrive in the background. But that would require a projector that would do such a thing. I think what would be an even better scenario is that, since Thunderbolt devices are meant to be daisy-chained and have 2 ports for that purpose, a 'standard' thunderbolt projector could have a homebrew device chained to it, that the presenter knows nothing of. (Hidden, explained as something else, etc). Then this standard-made projector can be made to be a malicious one simply by daisychaining another device on to it that could copy the contents of the presenter's hard drive.
