[Telepathy] Encryption and OTR

TLS/SSL will encrypt your messages from you to gtalk server. But gtalk 
server will decrypt it to send to your destination contact (and 
eventually re-encrypt). That means that Google can read your conversations.

OTR is a p2p encryption, so only the end destination can decrypt the 
message, any people between you and your contact will only see encrypted 
data. In that case Google won't be able to read what you say.

So IMO the question is: "do you trust your server", if not you should 
use OTR, otherwise TLS/SSL is enough. tbh if you don't trust your sever, 
you already lost...
