It could stop polling until the connection state changes

if you don't poll, you never know if the connection state changed.
My devious self is wondering if each computer can have an active TCP
connection to a specific address, like connected.ubuntu.com, with TCP
keepalives at a high interval (maybe 10 seconds). You don't have the
overhead of constantly opening and closing connections, but you do have
the overhead of actually keeping millions of connections open on the server.
This addresses none of the privacy concerns, of course, but it does give
near immediate notification when the network has died, no matter how you
get your connection.
