my concerns mirror steve's;
If this was a suite of web pages i dropped into a virtual folder on my own IIS server, yeah it would probably be a good idea.
If your example pointed to YOUR server, where i could test drive the interface, that would make me go farther than the in initial page.
I know i've built my own "PanicPage" on my web servers so that if the application goes down, i should, in theory, be able to connect to my sql server, which is not exposed to direct connections, and only from the web server itself.
so that's where i'd see a value with this; say i corrupted my main web site, and couldn't access it, or the code/css got so doinked i couldn't click buttons or something in the main layout.
