It required an app to be installed on the camera that was paid-for.

Apple had a similar situation once. I was among the thousands of people who paid Apple something like $10 to get a CD-ROM in the mail containing a single CODEC for something video-related.

Sorry for being vague, it was way back in the early days of OS X, so I can't remember exactly what the situation was. But I do know I still have the file in my archive, as I ran across it a few weeks ago.
