I have several questions on this:
1. Is Briar or Firechat open source?
2. Are they actually effective past "within a crowd" range? I.e. has the Bluetooth "networking" ever worked?
3. Is there any way to "secure" traffic?

2. https://briarproject.org/how-it-works/ any nodes can act as a mule to carry encrypted messages between "bubbles" through either Tor, WiFi or Bluetooth
3. The communications are encrypted all encrypted (at rest and in transit), only those who are added as contacts or part of a forum as a member will have the key(s) to decrypt the communication.
No idea about 2. though. Going with "unlikely".
