I like the idea intuitively (the idea that infinite discrete photons are required to mediate continuous fields from a single electron over infinite distances never sat well with me), so are they claiming here that there is a relativity-version of Maxwell's Equations? Does it require an additional spatial dimension to account for charge, or does it operate it on the same spacetime as gravity? Regardless, if I'm understanding this nontechnical overview correctly, it's a large claim requiring a lot of work. Probably worth a Nobel Prize if it they actually pull it off.
