Very interesting, but it's far from having the features required for an actual web server. GET-only is very limiting, for obvious reasons, and I assume that this system of using a redis queue wouldn't work for file uploads without a lot of hackery? Or am I missing something?
You could still handle file uploads and other complex requests traditionally, and only use a queuing solution for the most important traffic. Then, at least part of the site would stay up during upgrades even if corners of the site went down.
