Comment (by arma):

 Is this the right layer for solving the problem? How many people actually
 have their network interface go away, vs just go out of range of the
 wireless access point?

 I've always thought that the right approach here was to distinguish "I
 seem to not be able to reach anything" from "I can reach some things but
 not others", which is tricky to begin with, and extra tricky when you
 consider the time component (if you can't reach anything for a while, but
 then you do reach something, you cannot learn just from that which
 situation you were in).

 Or to turn it around, if you build the OS-specific code to check if the
 network interface goes away, is it now any less necessary to solve the
 problems I raise above?
