I know that wikileaks' "torrent the encrypted archive, have the decryption key on a dead man's switch" approach didn't exactly work as intended, but it's starting to seem like a relatively good option again IMO :S
How do you know Assange's hide-out is safer than Snowden's?
It's also interesting that Snowden likely has more freedom. At least he can move around Russia, while Assange is stuck inside a room. (security vs freedom)
It worked fairly well, just not as intended (Unless I'm mis-remembering, the intention was to keep the key secret while wikileaks released small amounts of info at a time)
