Hey this is interesting! Did you notice a significant difference in performance using this technique over running the compiler from the command line? There has to be some overhead in memory, but performance might be acceptable. You should probably cache down to .css files for production purposes, but that'll involve handling expiry. Either way, it's a really cool trick though. Thanks to this, I might try to push my Sinatra image resizing script into nginx+lua instead.
