Yeah, I didn't have any current expectations about the privacy, anything beyond security-by-obscurity which is absolutely not reliable for any important private conversation.

I'm pretty much chatting with complete strangers on the network anyway, and the usefulness I see is as a secondary communication band if traditional networks aren't available in a crisis. The PSK sounded more like a channel filter than an encryption mechanism to me anyway (I hope my past comments describing meshtastic were clear about this).

I'm all for identifying these flaws and fixing them, improving the protocol in future version so that maybe eventually it can be suitable for sensitive information than hobbyist blather or emergency info.
