Brad, thanks for your response! Looks like some significant technical barriers. I'm still wondering how well the IPBWiki inegration works, though.
Perhaps, instead of MediaWiki, we should be looking at another wiki, like PMwiki? Someone posted the details of their
abandoned PMwiki integration project not too long ago.
There doesn't seem to be an incentive for coder to hack out a Wiki mod, though; like I said earlier, it seems like RPG and "who's viewed this thread" mods are the most popular. Perhaps a bounty fund?
