This ain't for non-tech clients, Dras. It uses Github, Ergo. Bonus: Setup Instructions!

Nice share, checking this out for sure.
Nice... I've been too lazy to check out static site generators, but in general: (static generator) + git + (any hosting) is going to be fast and secure.
Free if you already have server space. Fast if you don't load it down with all manner of JS crap as per http://th3core.com/talk/web-development/doc-sheldon-post-gt-making-your-website-lightning-fast-isn't-that-difficult/
Tired of updating Drupal and Wordpress sites... If you have a tech-savvy team, you could even have multiple authors for your static site (as long as everyone is willing to learn a bit about git)
