Of course, my iPhone is currently showing an IP address in 10/8, and
though my EVDO card shows a global address in 70.198/16, I can't ssh to
it -- a TCP traceroute appears to be blocked at the border of Verizon
Wireless' network.  But hey, at least I can ping it.  (Confirmed by
tcpdump on my laptop: the pings are not being spoofed by a border
router.)
