Yeah, i saw that one. Problem is you will need the application running in bacground all the time to get notifications if I understood correctly. I see many applications without that kind of restraint, and that was really my question, will the mobile workers alway have to run the application in background, or will it be possible to get Notifications even when the app is closed? For some users this can be sporadic use, and then you may forget to open the app, and therefore miss something...
