// AO shadowchat feature menu including bootstrap network server list browser, chatroom list on each server, and chatroom interface
// Called shadowchat because no record is kept of the chat messages, and all connections happen E2E over tor
// As this feature gets build, sensible standards must be developed around when tor addresses change hands, when users authenticate, etc
