I share the sentiment, but it sounds like this is full-blown PDF with DRM support obtained by licensing Adobe code. It is interesting to see if Kindle can be registered to work with ADE (to download DRM-ed PDF's). It is also interesting that ePub support is optional in "Adobe Mobile Reader" platform.
I hope that Adobe is not having second thoughts about ePub. That would be very frightening news.
