Hi Michael,
Thanks for your questions. In short, you're spot on. Please keep in mind
that none of us are lawyers (as far as I'm aware!), but this is how I've
seen others interpret the rules in similar situations in the past.
The Project Aon Licence requires that users only download the files
directly from projectaon.org, which means they can't be bundled in an app.
However, there is no *technological* difference between a web browser
handling the download, and any other kind of software doing the same thing.
The user must accept the Licence before downloading the files. Beyond
giving them the opportunity to do so, I don't believe that you as the
software author are responsible for any of the licence terms. (Returning to
my browser analogy, Mozilla doesn't have to do anything about my compliance
just because I use Firefox to access the website!)
As for presentation, yes, this is quite open-ended. The text of the books
includes all copyright statements and Project Aon credits, so as long as
this is displayed at an appropriate place in the app (e.g. when starting a
new game, or in the same place as software author credits), I don't think
any other attribution would be necessary. Of course, if you want to give a
hyperlink to the Project Aon website, it'd be appreciated!
Lastly, if you do go ahead and develop an app, playing aid, or other
related software, we'd love to hear about it. A number of such projects
have been undertaken in the past, with varying degrees of success.
Thanks again for your interest,
