Does anyone know of any work related to automatically making arbitrary "look" like, say, an HTTP session? I'm thinking of something that would automatically encode a VPN session as a valid, renderable HTML document (and not via the trivial way of just gzipping it and making it look like an HTTP compressed document, as I'm sure that would still be easy to block.) It seems like this should be possible, albeit with tons of performance decrease, but I can't find anything.
