Is it possible to share a .ipa file between iOS device users who have purchased the app? The reason is we do not want to download the app (especially if it has a large file size, like 1GB).
For example, User 1 has purchased 'Scrabble' and User 2 has also purchased 'Scrabble'. User 1 has a good internet connection and finished downloading. User 2 has a bad internet connection. In this case, User 2 would benefit by copying the .ipa file to his computer (if Apple allows). Since both users have purchased the application, it is not piracy or illegal.
I just don't have two accounts to try and I don't know where to look for the answer. Answers or a link to read would be appreciated.
