When the cable is down there's the verizon usb stick (which this point 
can be into the router and serve the whole house), when verizon is down 
there's t-mobile handset. when t-mobile is down there's a workphone with 
at&t.

When the cable/verizon/t-mobile/at&t are all down for any signifcant 
length of time, I expect to be digging my neighbors our of the sorts of 
natural disasters that befall California and listening to the radio and 
maybe 2-meter.

I'm going to be somewhat contrarian, connectivity/availability with 
cloud services is important, where you access them from not so much. I 
doubt very much that reliance on the cloud drives multihoming for 
end-sites/consumers, it drives a demand for connectivity diversity so 
that one failure mode doesn't leave you stranded.
