#
# This script provides a complete push-to-talk (PTT) intercom solution using:
#   - Murmur: The Mumble server (can run on one kiosk)
#   - talkkonnect: A headless Mumble client for push-to-talk communication
#
# Use Cases:
#   1. Server + Client (All-in-one): One kiosk acts as both server and client
#   2. Client Only: Connect to an existing Mumble server
#   3. Server Only: Set up a kiosk as the intercom server
#
# Other kiosks or devices can connect using:
#   - talkkonnect (Linux)
#   - Mumble desktop client (Windows/Mac/Linux)
#   - Mumble mobile app (iOS/Android)
