To be honest, I'm wondering if this is something related to UA at all. What we are actually saying here is that when there is an emergency all possible channels (including Internet) should be used to notify about the emergency. Connection to a network (being it the Internet or any other network) is something in control of the OS. Also, visibility of application is something in control of the OS (you don't want to miss your earthquake notification just because your were watching a movie and not looking at (or not using at all) your browser. I also think that most devices are connected to internet also when not browsing. So it feels to me this is something to be handled at OS level, if it needs to be robust. And at a network protocol level, to make sure all networks you may connect to (broadband, DVB, others) provide this kind of functionalities (many already do). /g -- Giuseppe Pascale TV & Connected Devices Opera Software
