I doubt web 1.0 message board software takes a herculean feat of web design, but I don't know anything about that stuff. The page source here gives you the HMTL for any given page but it doesn't tell you about what goes on in the back end. And hosting it would cost more money of course.
Like you said though, boardhost is practically the only host left doing this style of board properly and they could pack it in at any time. Might be up to us weirdo hobbyists to save the day.
