Sending App-generated Requests to all users of an app

Question

Is it possible to send an app-generated notification request to all users of a canvas app? I'm currently sending requests to individual users, but not the entire user base. I do not want to simply loop over all users and send an individual request to each. Furthermore, that seems SPAMish. In fact the whole concept seems SPAMish, so I wouldn't be surprised if the answer is simply, 'No, Facebook won't let you do that.'

Answer 1

You could send to 20 users at a time with batch requests.
