estream II then? Did anything that came out of estream end up being used outside of proprietary product lines? Even Salsa is pretty well ignored in favor of Chacha. Are any governments using any of the estream ciphers internally?

ChaCha is just a minimally updated, hardened version of Salsa20, by the same author as Salsa20.

It's a weird question to ask, I think, because of the modern ciphers in wide use, the only non-AES cipher (heh) is an estream finalist.
