Is the Empathy Desktop Sharing through Telepathy Tubes encrypted/secure?

[onyxwolf]

Telepathy Tubes sounds a lot like a tunneling protocol, but I can't find a straight answer to my question...

When you share your desktop through Empathy's new Share My Desktop feature, which apparently is possible through Empathy's Telepathy Tubes architecture, does it encrypt the session like a tunneling protocol does?

To go even deeper, which algorithms/encryption technologies does it use?

No one knows? Hmmm... any suggestions on somewhere else we can post this question? I would hate to send non-encrypted credentials over a session that could be easily hijacked if the only thing that "telepathy tubes" does is a simple reverse NATing kind of thing...
