I am not sure if this board is interested or not, but I have some friends who run a message board for TekNap (A popular irc/napster client that is fully programmable). They were able to add a bit of code to the board to allow the forum to display tabs and spaces. If you are interested I can get the code for you (it's only a few lines). The main reason that I am suggesting this is because I find code a LOT easier to read with tabs!
