Add an authentication or pairing mechanism

[GoogleCodeExporter]

Feature request:

I would like to suggest a pairing mechanism that uses the camera and a
generated QR code displayed on the server.

The data in the QR would be used as a public key to facilitate a symmetric
key exchange. Then AES could be used for the remainder of the session. If
the keys were stored on both ends, the handshake would only need to be done
once.

Optionally one could opt out of the encrypted connection on the server.
