If anyone's curious, DVDJon points out that the root USB Node is still identified as "Pre, " so we very likely could see another round of these shenanigans in the not-too-distant future.
Of course, iTunes video is still wrapped in DRM, so we'll see if DVDJon has any tricks left up his sleeve to make it play nice with non-Apple devices, but for a first shot out of the gate it looks like extremely promising -- too bad it's Mac-only for now.
