I just love it when a problem has so many good solutions from which to choose! Thanks so much to all who responded. I think I'll try a couple of the suggestions. Eventually, I'd like to develop an "OPAC on a stick," so to speak, a flash drive with a minimal Linux distro on it. Boot from it, it takes you through a series of questions about your network, your catalog URL, etc, and when finished, you have a working OPAC. For remote management, there's always SSH, but I'd throw in Ajenti and kill the extra TTY logins to prevent possible patron mayhem.
I had looked into Porteus long ago but I seem to recall having an issue that caused me to abandon it. While I'm sure that's no longer the case, I prefer not to have to set up another server. I also like the idea of having a proxy server return custom messages, but again, if I can achieve the desired result without an additional system to maintain, that's my goal. I'll report back on what my machinations yield. Thanks again. Have a most excellent weekend, all!
