The Serial Time Link Protocol (STLP) looks really cool to me - I've thought for awhile that the next-gen in audio gear would be more modular front ends that sit on top consumer protocols, which is where things are moving in broadcast/commercial audio installations today. I can imagine a whole host of consumer and professional devices that solve real problems at lower costs than we can today. Really interesting stuff. edit: one weirdness, STLP has a recommended packet rate of 62.5kHz (actual quote "A Router shall periodically transmit a Serial Time Link Packet on TMU_CLK_OUT. The period between transmissions is implementation specific, but it is recommended that a Router transmit a Serial Time Link Packet every 16 μs"). If the only application domain (besides compliance testing) is audio, how did they arrive at that recommended rate, where it is rather different from standard sample rates (44.1k/88.2k and multiples of 8kHz)? I'm not sure how that affects clock synchronization.
