Neat but hardly general?
OK, I've read through their full paper - and it's interesting, I don't think it's going to do that much for general computing, but regexp stuff, hmm very neat - I mean ideal for trawling through intercepts at high speed,
or Layer 7 switch stuff perhaps, and I'm sure people will come up with funkier uses for it - but it doesn't sound a useful way to do really general stuff, and while there is a lot of talk about 'automata' this is more normal finite state stuff than anything too funky.
And since I really couldn't see any links in the Register's article, here are the two I found:
