Yes, this is the same paper we were discussing here.
I think it's an approach which is very worth looking at. I've always thought that locality/spacetime itself might somehow have to go in the next revolution in physics (though I admit that this view may have been somewhat influenced by doing twistor theory in the past !).
This deemphasis of spacetime is also the case with the scattering amplitude stuff of Arkani Hamed et al. This is producing real results for gluon scattering (admittedly only for N=4 SYM at the moment, but you have to start somewhere....).
