Interesting yes, but dynamic to static generators/caches are plentiful. Almost every framework/cms has something like this. I'm the current maintainer of Boost - file caching for Drupal. IMO Boost offers more to the site admin then Nanoc: it supports Apache, Nginx, Lighttpd, & IIS; Caches HTML, XML, CSS, JS, & JSON. In a test, the Nginx version of Boost is faster then Varnish. Boost is also tightly integrated with Drupal, offering smart flushing of the cache and a multi process crawler. Nanoc in comparison seems to add more administrative overhead to your sites work-flow; it should try to be smarter to make the web admins life better. Also, not having a dynamic language on the web server severely limits what's possible; a simple contact form has to be handled separately, thus making any site built with this even more complicated IMHO.
