Hi Jim, I originally read this section when implementing licensing:
Caution: Per-device licensing is not recommended for most applications because: - It requires that you provide a backend server to manage a users and devices mapping, and - It could inadvertently result in a user being denied access to an application that they have legitimately purchased on another device. I didn't implement this because of needing to have a backend server. Also, at the time, my app was more consumer focused, and therefore I wasn't too concerned since the average user may only have 1-2 devices (phone and a tablet, etc). Are there any paid services that offer this as a backend? I haven't found any. I did find a PHP project (http://code.google.com/p/ marketlicensing/) that would serve as a starting point. You'd have to keep a database of user devices and identities, and that brings in security and privacy issues into the mix. -Kevin On Sep 1, 5:51 pm, Jim <[email protected]> wrote: > According to the documentation, if you implemented the licensing > correctly, it will not allow installation on multiple devices for the > same license.
