The Sticky Team had a Live Gaze demo that could run locally. Initially, it was setup to be hosted online for the sake of accessibility to demo to clients as long as there was internet connectivity. We needed to password protect the page since it was available in the public domain. We have the URL hidden from search bots. But the URL was still clearly visible to any viewers, so we went with a hacky password lock.
