An interesting note...

I was just contacted by a publisher who was researching how an ebook got
leaked and distributed by a pirate before the release date.

What I found most interesting was this: the epub (which was the source file
stolen" was converted via Calibre to PDF before being distributed...

This is NOT a discussion about piracy or DRM - this is meant to be an
eye-opening situation...

Despite your view on piracy, most pirates aim to make content as widely
accessible as possible.  It was their determination that it was better for
popularity to release the ebook as a PDF than an epub...

Granted, when you buy from a digital retailer that immediately loads the
ebook into an app, format doesn't matter, but what it seems here is that
when it comes to sideloading, epub is not seen as a good format - which
means that anyone attempting to sell epub files that does not have an app
that directly loads their content is at a major disadvantage...

This is something we should seek to avoid with PWP - if it is not going to
be as easy, or easier than PDF, it is not reaching it's goal...
