Frank, Thanks - that's a neat feature to add. It does not work for my current requirement (the entire webapp is down at the time), but there are definite times when I want the webapp up and only limited access (e.g. checking out a just installed/upgraded application).

We had a two-hour window per day when the app was unavailable because background tasks were processing. The server was still up, and so was the app technically, but it was not available. I wrote a filter to take care of this. I had a flag in application context to tell if the app was up or not too, so that if I had to make the app unavailable during a time when it normally was available, I just set the flag. I also defined a single user that was still allowed to get in (another context parameter). This works out great. -- Frank W.
