Are CB Privates and CrazyTicket Shows Really Private?

[ptg]

I am confused by how much of what appears to be private on webcam sites is actually truly private. The underlying streaming technology that is apparently used on these sites is RTMP, but the stream is not encrypted? When sites like MFC and CB enter into a "private chat" mode, how is that actually being implemented? Are they sending out the stream to even people who are not in the private chat and encrypting it? Or are they simply not transmitting any stream at all to anyone not in the private chat?

CB has an app known as "CrazyTicket" that is used to do ticket shows. How secure is that? Does it send an unencrypted stream to all users? It's not clear to me is something like CrazyTicket being implemented as some kind of password protection inside the web browser, but the underlying RTMP stream may in fact not be protected at all?
