I want to sell a power point file. My problem is that this file obviously can be endlessly replicated and distributed for free.
I need someone creating a reasonable way that every time the file is opened it will ping my server and ask for permission toke. Also the file must be connected to the mac address of the device it uses.
!!!IMPORTANT: don't use generic application... give me a short overview what you plan to do to make this happen
