Sounds like a great idea in theory but would require OS support or a
dual-hotspot setup that provided for both options until support was
expected.
Until such time it's simply unworkable.
That and as mentioned in my previous post, the setup we have *just
works* for users who don't have the permissions to change off of a
static IP and use DHCP on their laptops.

This really should be a DHCP option which points to the authentification
server using ip addresses. This should be return to clients even
if they don't request it. Web browers could have a hot-spot button that
retrieves this option then connects using the value returned.
No need to compromise the DNS or intercept http.
