Why do you believe that the limits have been exceeded
As long as the receiver has the bandwidth to accept all the data thrown at it without building up a queue then the system is stable under those criteria.
One would think that the setup is feasible since it has already been demonstrated in the lab, as opposed to just on paper. Of course the commercialization of the technology is yet another story.

No this is still just test result in a lab experiment, it will take many years to finalise and commercialise a final product that could then end up in the home (if ever).
I have seen plenty of really interesting lab experiments that never got anywhere near a final commercial product stage (yet).
For even more interesting developments try an internet or CR4 search for data teleportation.
This doesn't surpass Nyquist. The technology provides a way to put multiple light paths onto one carrier...more than the two conventional polarized light paths. This is great at the service provider level, but the bottleneck at your home will still be the same unless we revert to fiber optic NICs...updated, of course with the vortex technology.
I imagine we could see satellite and terrestrial Netflix streaming with fewer data hits.
Of course, with all of that extra bandwidth, everyone will come up with ways to fatten their code and relax their compression algorithms until we are overloaded...again.
Have we surpasses the Shannon and Nyquist limits. No, each polarization is a separate channel of information which is limited by the Nyquist limit. This just allows more parallel channels in the same light beam.
Is this setup feasible?
That's a good question. My limited understanding of this is that it only works in a beam (laser beam or microwave beam). (Somebody please correct me if I'm wrong.) If that's the case, I'm not sure how it would work with wifi, which is omnidirectional.
