Interacting with a device that is no longer on the network

[buchanae]

1. Put your device on the network, as usual

2. Refresh the device list and see your device in the list

3. Remove your device from the network, e.g. turn it off or disconnect it from the AP

4. The device should still be in the device list, because you haven't refreshed the list yet

5. Without refreshing the list, select the device from the list. The device will stay in the list, and you should get "no files"

Something more graceful should happen. Some indication should be given to the user that the device no longer exists, and it should be removed from the device list, without triggering an entire network scan.

Perhaps every X or so seconds we ping out to the known online hosts to determine if they are online or not?

This is more like exception handling than polling. This should be handled without polling, because the user could always click in between device pings.
