Hi Paelleon,
At the outset, I'd like to say that I'm not a lawyer, and as far as I know, neither is Alderaine (feel free to correct me there, mate
). So while we'll offer you our best advice, you can't really rely on what we say if push comes to legal shove.
Now that the obligatory disclaimer is out of the way, let me offer an opinion on the matter that differs a bit from Alderaine's.
About presenting the books in a different wayThe Project Aon licence does not prevent you making any of the stylistic changes you specify. Our remit is to adapt the Lone Wolf books and other works into "Internet Editions"; in practice, these take many forms, including the HTML books, PDFs, and of course the source XML files.
The Project Aon licence doesn't even touch the subject of reader software. It has no more effect on how "Lone Wolf Reader App 9000" works than it does on how Mozilla Firefox or Adobe Reader work; these are all programs that can be used to read Project Aon Internet Editions. Therefore, you can introduce whatever stylistic elements you like into your reader software, including extra/alternative illustrations, rearranged section presentation, etc.
Alderaine is right about how things are "usually" done, preserving some of the feel of a gamebook; but you specifically say that you want to move away from that a bit, and it's only convention, not the Project Aon licence, that would stop you from doing that.
About modified formats of the books themselvesThe Project Aon licence is targeted at readers, not at the PA team (and as soon as you get into the business of tinkering with PA files, you're part of the team
); it doesn't really say anything about how we can adapt the books into Internet Editions, or whether and where we would exceed our mandate if we offered files structured the way you describe. But as you say, the database and back end could still work with section numbers and the like; what really matters is how it's presented to the reader.
Our XML files are pretty flexible in that regard -- nobody can dispute that they are a faithful adaptation of the books, but your software could read and digest them in such a way that it does exactly what you suggest. (Oh, they'd certainly be more useful like that with certain modifications, but there's sporadic ongoing discussion about how to produce a "common navigation format" for software readers to understand the books.)
So in short: there is nowhere that you would run afoul of the Project Aon licence, or risk overstepping the Project Aon mission, if your stylistic changes are in the software's presentation rather than in the book files. And that's exactly what you've described.
About a Facebook appAh, here's where the bad news starts. The Project Aon licence very clearly states that only specific "Distribution Points" are allowed to distribute PA's Internet Editions; right now, that means the projectaon.org website. Even showing the PA pages within a frame on another website's page is not allowed.
The Project Aon licence is, to borrow terms from the free software community, a "free as in beer" (free of charge, gratis) licence, but not a "free as in speech" (freedom, lack of restrictions) licence. Existing software works on the following principles,
not as a matter of convention, but as a matter of licensing:
1. The reader agrees to the Project Aon licence.
2. The reader downloads files containing the books (in some format or another) from our website.
3. The software digests the book files and displays its digested layout to the reader.
...or...
1. The reader visits an online play aid hosted on our website.
2. The reader agrees to the Project Aon licence.
3. The play aid accesses and displays the book files, which are also hosted on our website.
That pretty much precludes a Facebook app that in any way embeds, displays or redistributes the books, I'm sorry to say.
Edited to add: Just to throw some ideas out there...
You could perhaps write an online play aid that integrates with Facebook in some manner. For example, a Facebook user could display a "Lone Wolf status" on their page, saying "I'm a Scion-Kai, I've died five times, and I'm currently up to section 112 of The Prisoners of Time."
This would fetch its data via some Web API from a play aid hosted on projectaon.org; whenever a player/Facebook user continues their saved game that they've attached to their FB account, friends viewing their Facebook page would see their progress updated. You couldn't play directly on the Facebook website, but clicking the status box would send a Facebook user to your play aid on
this site, letting them start up their own Facebook-integrated LW game.
Further disclaimer: I don't use Facebook and am relying on second-hand reports of its operation in concocting this scenario!
