I have considered this approach many times, and am still doing so. It solves many problems, for example removing the need to have two different in-app purchasing systems for Google and Amazon and removing the strange license check timing constraints. Such apps are common enough now that I don't think the confusion factor is still an issue.

The only real problem for me is as Kaufman said below: the ease of piracy. Unless the unlocker app changes frequently perhaps with the main app, the scumbag pirate need only crack it once. It is small, making the analysis easy. On the other hand and as I said above, perhaps it isn't worth worrying about because the bottom feeders will find a way around anything we do regardless.

You are correct in that apps that apps that use an unlocker will not have a problem, but apps that are really a separate app will not be able to write to the data directory of the non-pro version if it is stored on the External SD card.
We would use an unlocker, not a separate app.

2) Many apps have very limited amounts of data. an app like Supersu doesn't need to store anything on the external SD card, and even if it did, it wouldn't be more than a few meg of data. If a pro version of an app was installed, it could just copy the few meg of data and the user would be none the wiser. I have almost 5GB of books on my SD card. Some people have more and some less. It would not be feasible for the pro version to copy that much data from the standard version's directory to the pro's version. Chances are, Chaley would just force people to re-download their books.
This is what we do with the demo CC app, assuming the person changes the default books folder. However, given that it is limited to 10 books, the possible second download isn't a big deal.
