I posed this question to an irc buddy up in Toronto who has done work 
with cog. sci., and he
pointed me to a Google tech talk given by one of his professors at the 
U. of Toronto...

"The Next Generation of Neural Networks"

The document classification experiments are pretty amazing...maybe these 
types of neural nets would work well for spam classification?
And could learning be speeded-up (and more RBM layers added) with the 
use of CUDA?

( I asked said irc buddy, who says "Bayes is good enough".  But: I wonder? )
