There is a draft rfc for using Chacha20-Poly1305 as an alternative cipher for TLS. Generally it is a good idea to have some alternative ciphers available. So it would be nice to get something like this into TLS sooner than later. AFAIK this draft rfc is only implemented by chrome and google. Of course, I'm not a cryptographer, so I don't know, if this is really as good as it looks.

Sadly, it is expiring today.
