I have a pile of Logitech Squeezeboxes running multiroom audio here, and it does all this sync stuff too, with much of that tech originating from 2001-2004. Things were tight between them and Sonos until a Logitech pulled a Logitech and crippled the hardware lineup before killing the brand. I now wonder if these patents had something to do with it.
