I found it used in professional print mastering where the large-format printer(s) which printed the masters were connected to an NT3.x server by VideoLAN using ethernet cable, then a second NIC having regular ethernet drivers connected the NT box to the artists' network who were using Apples.
With the amount of data they were sending in one direction once it got started, they were really streaming and apparently multicast was a click away when you wanted all the printers to print the same thing at the same time.
Naturally this was well over 20 years ago, but I imagine there was some nice wizardry to get old computers to perform so much better than they could as office machines.
Probably still have that driver somewhere, IIRC the driver would install in XP (but only to one of the few NICs in the INF file) but the pro printer app did not have an XP version and even the NT4 version would not install in W2k or Wxp.
