Yeah - I’ve heard one of Stu’s talks about their theory. It seemed like lots of handwaving was involved, but I didn’t spend enough time researching to actually understand it. On the other hand, he is an actual scientist, so while his theory sounds rather optimistic, it definitely treats quantum physics from a scientific perspective rather than the usual quackery of people who don’t have a clue about what quantum even means*. He at least attaches the quantum stuff to the chemistry of some sets of molecular structures in neurons that are small enough for it to be reasonable to have a bit of quantum randomness that might be enough to flip a bit on whether a given synapse fires or not; it’s less clear how there’d be any quantum entanglement between microtubules in different neurons involved, or how there’s anything related to consciousness involved in it, as opposed to the same kind of uncoordinated randomness you’d get from a bit extra heat.
Meanwhile, I just got an email today with a call for abstracts for 2014’s conference, which will be in April in Tucson. Plenary speakers will include Susan Blackmore, Ned Block, David Chalmers, Karl Deisseroth, Daniel Dennett, David Eagleman, Rebecca Goldstein, Stuart Hameroff, Christof Koch, Henry Markram, George Mashour, Sam Parnia, John Searle, Petra Stoerig, Giulio Tononi and many more. And Deepak Chopra’s giving a talk 
* (There’s also a non-quackery reason for discussing quantum; it you philosophically want to have your mind have Free Will instead of being a deterministic (if incalculably so) side-effect of materialism generated by the meat in your head, and maybe even have a Soul involved, there needs to be some non-deterministic process attached to the biochemistry, and quantum effects are the only hook physics gives us to hang that on. It’s tough to get from there to a scientific theory of how the Soul knows which neurons to trigger, and most of the people who talk about quantum don’t actually try.)
