I don't believe Mister Miller has licensed such. With the exception of the Megatraveller PC games back in the late 80's, I don't think he's ever provided a license for electronic products... which is why the e-books surprised me when they started appearing; they're questionable under the terms of the license posted on the FFE site. But since they've been available for a few years now and there don't appear to be any lawsuits from FFE in the works, I suppose MWM has chosen to regard them more as books than as an electronic product. It's only fair, since he's also gone somewhat that way himself in the intervening years.
