The idea of just utilizing the bidirectionally continuously active transmission lines of 1000BASE-T to essentially mutually PLL over the highly symmetric please delay wiring repurposing the existing carrier/clock recovery and garnishing with some actual data on top (clock comparing/time sync, configuration), is just ingenious.

IMO this counts as hacker spirit already.

Just a shame the hardware is completely out of the "fun project" price range, even if substantially less fancy components would suffice for most non-CERN use cases of White Rabbit... e.g. the mentioned synchronous Ethernet, and utilization of single frequency network [0] capabilities for WiFi.
