Comment 1 for bug 324484

I recently have had another idea and it seems related so I put it here: maybe the Universe Manager can be aware of the Internet status. When there is not Internet, it won't update any item source which will involve Internet access; This requires the item source to have extra property telling UM if they needs Internet access during updating. Regarding how UM can know about the network status, maybe the system-wide NetworkManager can provide some information over DBus?
