[Dnssec-trigger] dnssec-trigger at Hotel hotspot in Vienna

Hi,

I had an issue today at an hotspot in a hotel in Vienna (using MacOS X).

The hotel has an captive portal WLAN. DNSSEC was working using the
WLAN DNS (from DHCP), so DNSSEC-Trigger configured the use of the
Unbound DNS on localhost. However the captive portal login page was
only available when using the DHCP supplied DNS Servers (non-delegated
private DNS name for the portal page). So the only way to do anything
else then DNS (I know, who needs that :) ) did not work in this setup.

Not sure how this can be solved, maybe by having DNSSEC-trigger to
test a well known webpage of port 80 to detect a captive portal. MacOS
X 10.7 now also has an automatic captive portal detection (ported from
iOS). Not sure if there are APIs available to use the function.
