I hardly call this compelling proof, especially since there has not been any follow up since the posting. Still, I still hold that it is well in the realm of feasibility, it just wants for someone willing to do it. And possible have to fend of cease and desist. Or worse.
I was originally more optimistic, based on how quickly Linux was up and running on the latest generation iPods. But it occurred to me that despite the attraction of the wifi hardware, the ad-hoc DRM may make this a bit more of a snarl. Not technically but that the labels who are partially responsible for this scheme and in a later article that shows the DRM is even more crippled would undoubtedly not understand who running Linux is non-infringing and not a threat.
