What I know is that, as https is so easy to use, there are plans to make it serve covert traffic. So you would make a request to https://www.friendlyproxy.com with an extra header somewhat like What-I-Want: http://www.bannedsite.com and have "friendlyproxy.com" serve you the document you originally wanted.
I forgot the name of the project, though. I believe it was from an American university
Besides, with this new wave of government carrying MITM attacks, I don't know how useful this techniques will be.
I wrote something like this to circumvent our filtering proxy at work. I didn't open it up to the public because I was worried about being responsible for their traffic, though.
