Very cool.
Even though I intend to stick with ADE 2.0.1 and EPUB as my main format for as long as possible, with K4PC 1.17 and KF8 as a backup, it's nice to know that KFX's DRM has been broken.
The conversion plugin says that KF8 is superior for conversion (because the book is one file and the format is well known, I assume), but still, it's better than nothing if KF8 and/or EPUB ever ceases to be distributed. While I'm sure EPUB2 will be around for a long while to come, I can see Adobe, at some point, requiring ADE 4.x as the minimum software to download the books.
(Almost forgot... Kobo KEPUB's, un-DRM'ed, converted and then cleaned, can also be made into regular EPUB's.)
Thanks to everyone working at this stuff
