My question was a bit rhetorical.
it's not *possible* for an OS to reliably know if there is an Internet
connection
without either polling a known site (bad idea to implement in an
operating system, it'd be a DDoS to the poor "known site"),
or having a zillion plugins for the different ways an Internet
connection may be set up (eg. for my connection, you'd have to
HTML-scrape http://192.168.100.1/, the web configuration page of my
Motorola SurfBoard cable modem), which is totally impractical.
