This seems like it'd be useful for almost all situations except for DB schema changes.

Those of you using Tomcat JEE apps, and deal with downtime, how do you handle putting up some sort of "we're down" page? What strategies do you use?

Same trick. Configure the proxy to forward to a static page instead of Tomcat.
