That works quite well.

I've been doing the same for http://einaros.github.com/http-tunnel for some time now; it essentially establishes a tcp tunnel over a custom http upgrade protocol and allows reverse http / https requests to pass through that - thus allowing nat'ed or heavily firewalled hosts to publish web stuff through a public address.

Cool! I've used HTTP upgrade in the past too and it's quite useful. My main goal was to demonstrate the usage on a popular PaaS.

It's always interesting to see less known features of a technology used in an original way.
