He gives multiple solutions in his post. The first does not address the second case i present in the original problem (many apps, single add-on). The second does not describe in any detail the nature of the solution. These could be combined in some way to give a more complete solution, but more details are required and i'd rather have him fill them in.

I'd like to have other, complete solutions, and would welcome proposed solutions that qualify, but i'm not going to add solutions to my brainstorm that don't fully solve it.
