Business models based on the compiled list at http://news.ycombinator.com/item?id=4924647. I find the link very hard to browse, so I made a simple version in Markdown instead.

A little utility to allow simple redeployment of Clojure web servers with zero downtime, and without the need for a proxy or load balancer. Just wrap any port-binding calls, and the utility will auto kill pre-existing servers as necessary. *nix only. Based on the blog post by Feng Shen, http://shenfeng.me/fast-restart-clojure-webapp.html
