	// Pros:
	//  - works with any protocol (does not require RTCP or NTP)
	//
	// Cons:
	//  - synchronizes only clock speed, but not position; different receivers will
	//    have different (constant) delays
	//  - affected by network jitter; spikes in packet delivery will cause slow
	//    oscillations in clock speed
