As far as I can se are they specifying Cat5. That almost certainly means they have a large number of twists/inch which gives a good protection against M-field induced interferance. E-field interferance is not such a large problem as the data is transfered in differential mode and the CMRR is rather high in the equipment.
It will be most interesting to se how they plan to evade the EU EMC directive on this one.
Spewing HF and UHF energy out on the power-line is something you can't do in a residential context. (Just think of the emissions being transformed backwards through the power grid.)
The main thing about this is how they have sucessfully made handover between each base-station along the route without cracks, mutes and dropped calls.
Would be interesting to see these guys go up agains the EU DECT-standard.

I picture Old NSA-Bob working the crowd, gathering who is at the local 2600-meeting using their under-the-skin-RFID-tags.
Suddenly, from nowere, his spook-gadgets emits strange sounds.
Yes! Its "Popcorn"!
