An adjacent paper by Deutsch suggests that the topic was not necessarily
long ago exhausted. Here's David's reply to somebody's comment:

There are no purely classical means in nature, of course. But yes, we proved
that in all phenomena that have hitherto been deemed to demonstrate
non-locality (in particular, EPR experiments and quantum teleportation) the
quantum information travels by purely local means, in decoherent information
channels (e.g. down a telephone line).
