(presuming first that these events can be propagated up to user space
through some kind of listen on a socket style API, something that I don't
think is possible _yet_)
I beg to differ a little. Considering the case with the machine has
multiple network interfaces, and a mobile IP (RFC2002 and
friends) capability, this kind of notification is crucial to smoothly
transferring traffic onto other available interfaces (think mobile pda
with ethernet & wide area cellular data). This is just one instance of
'middleware' style applications that would prefer not to poll this kind of
state.
