Interesting indeed!

Observation: This, or any tool like this (any proxy which can negotiate an SSL and/or TLS connection) could be used to give simple browsers, browsers that don't implement SSL or TLS natively, SSL and/or TLS capabilities...

(In other words, if I were going to write the simplest of all possible Web Browsers, a Web Browser solely for teaching purposes, then I'd intentionally separate its source code from SSL/TLS/encryption code. Why? Well, it would greatly reduce the lines of code in the browser, which would aid greatly in making that source code easier to read/understand. SSL/TLS/Encryption could be implemented in a separate local proxy server, much like the one above, and the simple browser would gain the ability to make SSL/TLS/Encrypted connections through it, while keeping all of that additional code separate... also, on that note, JavaScript processing (all browser code necessary to run JavaScript) could also be separated into it own local server...)

So yes, again, very interesting!
