All of which require authentication of some form, which the router 
itself doesn't have the credentials. But home routers do have a few 
different characteristics: proximity and local addressing. Maybe your 
work you pointed out might be applicable?

Of course, it could always have a bluetooth-esque "pairing" button to 
enroll devices that are allowed to log in, but that would require hardware.
