A lot of hotel and coffee shop captive portals use it for the login
and logout screens.  Don't know what the underlying software is, but
wander around London and hop on the wifi at coffee shops and hotels
and you'll run into it soon enough.

Tons of it in the US in hotels, airports, and any number of other places that folks have already mentioned. Why we are
