I like this. I could see this being extra useful for people not using CDN's if they could easily plug it into nginx, haproxy and such. Currently for proxies I look for the proxy headers and also use a list of known proxy IP's but that is obviously nowhere near as complete as what you built. It might also be interesting to test assorted configurations of SSH forwards and MitM TLS caching proxies such as Squid SSL Bump.

I guess for this to work best you'd build your own CDN and have as many servers as possible. I have always dreamed of an Open Source CDN managed by a nonprofit and dedicated to offering CDN services for free or for a reasonable cost.

If you did the timings by comparing to other protocols, like TLS or HTTP you could do this with a single server, but that's a bit more complex than doing it on the same protocol since you have to account for more stuff, but it could be done, at the end of the day, my idea with Aroma was mostly to prove that it's possible, thanks for the feedback btw!
