Now that was my last post!!
I'm not sure about this. It certainly seems that way from Adobe's site, but there are stories all over the internet about DRM protected ebooks not working under Linux - apparently the Linux community has been asking for DRM support from Adobe for a while. If it were possible for developers to do on their own, it seems like someone would have just made a DRM-enabled PDF reader for Linux.
Also, Adobe's ebooks site specifies that the software will work only on Mac OS and Windows. Of course, that could be simply because they don't want to point to any competitor's software for other OSes.
All in all, I can't tell whether anyone can create a reader for protected PDFs for free. It certainly seems that Adobe is more open than I gave them credit for, but I'm still not sure whether they're *that* open. In any case, it would seem like a good tack for Hanlin to take, since it seems Adobe isn't exerting Apple-like levels of control over their DRM, anyway.
