What is need is open protocols. Users can write their own implementation if they do not want to use the existing ones. WhatsApp uses XMPP according to Wikipedia, so you could implement your own according to XMPP, I suppose. You might also just use your own programs and protocols. If the messages are encrypted with the recipient's key then nobody else can know what is the message, but only that there is a message. So, you can implement encryption on client the server does not need to know about it. |
