I'm trying to determine what kind of proxy/tunneling method this guy is talking about. He are a few quotes from him: So what exactly is an "X/MTP" device and what port are they usually on? I can't find too much info online. The concept sounds very interesting, but I have to wonder if the author is full of it. He says there are over a million of these devices out there, yet there's hardly any info on them.While searching, I found a site referring to XMTP (XML MIME Transformation Protocol), but I don't know if it's the same thing he's referring to or not. I don't see how one could use that to tunnel HTTP traffic thru. It's not even an official protocol, so I doubt that a million people are using it, let alone many devices supporting it.
