Indeed, Seth Lloyd and Jack Ng are proponents of the idea of a discrete 
universe. If the universe is discrete, then most models of 
hypercomputation are meaningless, something that I believe would make 
computationalists really happy. In addition, in a discrete universe there 
is practically no free will as Wolfram advocates in his latest book (A New 
Kind of Science, Wolfram Media, 2002). Now, on the other hand, Roger 
Penrose in his latest book, entitled "The Road to Reality : A Complete 
Guide to the Laws of the Universe", gives some really interesting ideas 
regarding the discrete nature of energy. And finally, one should not 
forget that there is no experimental evidence in favor of the granularity 
of space and time!
