Proposition:So far, negociations had been blocked between France and the European Commission on the subject, with EC considering ebooks as a service and not a cultural product, hence not allowed to use the reduced VAT rate, whereas France (and Luxemburg) considers a book as a book, whether in print or electronic, in which case it is entitled to the lower rate.
On the other hand, other actors who would sell interoperable/open files would benefit from the lower rate.
My opinionI don't see it working at that level, since the big majority of publishers insist on DRMs, and any e-resellers who wants to reach mainstream customers will need to provide the DRMed files, hence restricting him to the High VAT rate.
On the other hand, if the granularity were per ebook, depending on the presence/absence of DRMs, it would work quite well, by forcing e-resellers to allow fine-grained per-title DRM activation(1), and publishers to restrict DRMs to where it really is mandatory.

(1)which is not always the case, for example Amazon and Kobo use the same setting for each ebook by the same publisher, except through KDP/KWL
