Thats an interesting concept, I wonder if Russia and China have their own standards/protocols to use?
I guess we could get the same effect by encrypting using 3DES, then AES, then blowfish, twofish and then RC4.

TrueCrypt supports cascaded encryption in XTS mode, see [0]. AES-Twofish-Serpent, combined with a decent password and Whirlpool hash algorithm (it is used for HMAC and for mixing the RNG) should be pretty secure, IMO. Anyhow, we don't have plenty of really good and checked publicly available alternatives for symmetric encryption.
