Hmmm... the instant I wrote that I realised there's no way that would ever be likely. I mean, it's ridiculous. It's an Emacs powered Apache instance.

Duh. Don't know how I could have missed that.

I'm sure you could run elisp scripts with mod_cgi.

But who needs Apache? Just M-x package-install elnode, and you've got yourself a web server.

I guess they could be forging the Server header...
