I've been doing some reading on this recently, and as far as I understand it, this paper is not going to settle the matter one way or the other. IANAP so take these notes with a grain of salt. There was an experiment done by a Chinese lab a few years ago, which seemed to support the effect, but when they re-did the experiment using an on-board battery instead of a power cable, the effect disappeared. So far noone has publically replicated this condition (i.e. battery instead of power cable), and either confirmed or disconfirmed this null-result, and I do not think this new paper will report any experiments using this condition either. There are however efforts underway to actually put one of these things into space in the form of a tiny satellite, and see if any thrust is produced there, which seems like the perfect experimental setup. All in all I think it is going to be years before we know what is what in regards to this technology.

Wouldn't this have the problem that the object will constantly being hit by particles (and the distribution of particles will not be random) and accelerated by these?

  yes but they can use data from pioneer to correct for it, especially if they are far enough from earth, also if the drive can be cycled, they can measure against the condition at rest.

"...There are however efforts underway to actually put one of these things into space in the form of a tiny satellite..." Neat. Got a link for that?

  The Cannae Drive is another implementation of the same idea. They say they'll launch a cubesat in a couple of years to demonstrate the drive. Their website doesn't have much information about it but here are some links: 1. http://cannae.com/cannae-is-developing-a-cubesat-thruster/ http://cannae.com/cannae-is-developing-a-cubesat-thruster/ 2. http://cannae.com/press-release-from-cannae/ http://cannae.com/press-release-from-cannae/ 3. http://cannae.com/cubesat/ http://cannae.com/cubesat/
