@alienghic @ohir @Andres4NY @KathyReid I can probably claim to know a bit about multicast as I wrote the host-side portion of the control protocols MLD/IGMP. BSD license Corporate Free rider effect: every time someone connects with an iPhone, my code runs. Apple integrated the code, I don't get a royalty, and any attempts by them to recruit me over the years have been... somewhat cack handed to say the least, plus they dicked over a now deceased close friend on some GPU driver code in the 00s.
