I would think you would not have to go back to the LAN once the WAN is picked
because:
Every time you open the app, you want to check the access and make a determination.
With an android device, I really don't think you want to keep the link to findvera.com
open all the time you are away. I would think you would open the app, do sometihng,
and then go off and do something else. When you do something else, the findvera
connection should close. I have found with air4vera this setup time is not really a problem
and that way you are not sucking up findvera capacity when you don't really care.
every time you open, you check LAN, if not avail, check and get findvera.com. It takes
a couple of seconds to make the connection.
