Actually, dpierron, cbarnett, regardless of my wishes, the code to decrypt LIT files is unavailable. Even in the open source domain. Basically, there are three different types out there. The first is very similar in protection to the second and both can be decrypted with the open source program convert lit, which I am unassociated with.
The third format, those you buy from the online bookstores and which require an activated reader, can be decrypted with the same program. But. I pretty much imagine you senseless people never tried doing so on anything -but- windows, did you?
Decrypting these kind of files needs to be done on the same computer as your activated reader...because it refers to some DLL's from microsoft. CovertLit uses those itself to decrypt them. These DLL's are also unsurprisingly enough not available on other platforms...
(Speculation, just thought up
Though maybe the pocketpc has them too...it has a reader after all...Hrm...
