This must be a pressing issue for future data hoarding. As far as I know the DeDRM people got a legal notice and had to remove their old solution for this, nonetheless it kept floating around on the web but the solution doesn't work anymore as it was for a far older version of LCP. Many e-book stores in the EU, and libraries, Netgalley, even Internet Archive, is switching to LCP. Is this only a question about when, or is Readium LCP as a technology a tough nut to crack?
I mean, Kobo is only "thinking" (and have been thinking for the last couple of years) about adding LCP support. It's crazy how we're somehow having to resort back to using Android or iPhone devices just to read our ebooks. And of course being bound to the store's or publisher's whims (like with the recent Amazon changes).
