So it isn't a shocker in the least bit that the FCC has granted a waiver on the mandate and now while operators are still required to make boxes with functional 1394 ports available to those who request it, the rest of the boxes can just support an IP interface instead.
We wouldn't expect this solution to replace human camera operators anytime soon, but it's certainly a viable method for adding angles and placing a bit more control in the hands of production teams, even after the fact.
