End-user approval? That means support calls, ISPs wouldn't like that.
I can believe something like this could be made to work, but I would think
hard about all the way that web sessions can get screwed up or hijacked
before I persuaded myself that a scheme was likely to work where it needed
to work (e.g., when connecting to a hotspot that hijacks all web sessions
until you log in) while not being subject to hostile spoofing.
Followups definitely to IETF-something.
R's,
