Hey Tim. You're correct that validating purchase with the market is a key piece of our solution. Figuring out how exactly to do that using Google's binary market protocol in an efficient way (try doing everything that AAL does in a 35 KB library) was a fairly significant dev effort. What's more, balancing license generation, market API security, cross- Android version compatibility, customization, etc., and you've got a nice little chunk of work that we put into this solution.
As for pricing, we'll see what the market will support. In our own single app Screebl, we "lose" about $100/day in revenue to pirated apps, so $50 seems cheap. I know that not all of that $100 will translate into sales, but some percentage will. My point is it shouldn't take long for AAL to pay for itself.
