There is another way that I know of but it is unsafe. VERY UNSAFE. If each client ftp's into some web space somewhere then the app will be able to leave information in the web space for you to read later. The problem with this method though is that the app will need to log in with a username & password and if people intercept this information then you can say goodbye to your web space which course, buggers everything up.
I dont know any other way apart from modifying one copy of the app for yourself to act as a server and then listening for connections.
