That sounds interesting, certainly. But out of curiosity, how would you handle the security aspect? It sounds like the utility of such a wiki lies in letting the user use the full power of Haskell for development & configuration (which has worked out well for XMonad) - but obviously that implies letting random users run arbitrary code on your host. Are you going to just sandbox the web server in a chroot or something? > If you are intrigued by this project and you have substantial experience in > designing Haskell-based web applications, please send me your resume and a > brief summery of why you are interested. > Regards, > Enzo Haussecker -- gwern
