What are you talking about?? Enterprise type WPA where you authenticate against
a back end server has been around for years, and with WPA2 it supports good
encryption, too.
And they
still don't have a decent mechanism to support the typical coffee shop
type access mode.
Well, you could use WPA(2) there too. People who don't have a working account
yet for the hotspot in question would then log in as guest, create an account
and then log in with that account.
But I would argue that the IETF in general has ignored access control to IP
networks and how this interacts with provisioning of addresses and other
information once PPP was out the door. Look at the backflips that are required
to provide ethernet-based broadband access. Although we can partially blame
this on the lack of uptake of 802.1x which handles the authentication, but that
still makes (IP-over-)ethernet-based broadband problematic because of its
point-to-multipoint model that isn't appropriate for providing services.
