The AP couldn't set anything w.r.t settings unless you connect to it
specifically and it has a cert that your browser trusts, at least assuming
the model where settings are persisted only for sessions using verified
certs (like what is done with SPDY today).
And then the browser (at least Chrome) will forget the setting upon the
change of network.
And of course, one could just set a cookie instead of doing SETTINGS, but
then we announce it everyone, even when not useful. bleh.

We'll talk about it later anyway.
