Unfortunately I realized this solution won't work. The device could be connected to a wireless network but not necessarily have Internet access.
So back to the drawing board...

When I tried testing it just now, I always got an empty value back in the reachability info, even when I had WiFi turned on. It looks like it's designated as "experimental", so maybe it's just not polished up yet.

This appears to return simply "127.0.0.1" when no Internet connection is available. If there is a connection available, it returns a list of all IP addresses, one for each available network interface. I'll be testing this out some more, but so far it looks promising.
