I had a similar idea, at least in terms of resilience. It was, basically, to compress each piece of content just so that the compressed version would be theoretically uncensorable.

Jon Lech Johansen did this with DeCSS back in the day [1], and the compressed version of the program was a prime number, which gave it a sort of "untouchable" quality.

Obviously, doing this for much larger content (i.e. movies and general videos) would be a challenge, and this technique might not be the best choice. Still an interesting concept, though.
