You can watch/listen to Arkani-Hamed's recent talk at SUSY 2013. At around 2:00, he says:
locality and unitarity emerging just as algebraic and geometric properties of this object
At around 6:00, a written slide describes his strategy:
Reformulate QFT, Eviscerating Locality + Unitarity -> see them arise as emergent phenomena
He goes on to discuss this subject in more detail.
Also, (somewhat technical) slides from his former student have a section called "Emergent Locality and Unitarity".
I recently ran across a rather interesting result while browsing the Internet:
Physics Discover Geometry Underlying Particle Physics
Unfortunately, I'm still at the point in my education where my best response to new physics is "cache for later," and the fact that it claims to eliminate locality/unitarity seems decidedly odd to my mostly-untrained mind. I notice I am confused, and that LessWrong has a rather large number of trained physicists.
