Coachella was easier to acquire because they had the stream running for hours before HTDA. One could have determined by that point the stream's URL and then be prepared to record the stream with the program of one's choice, as well as running a test recording before hand to make sure that everything worked. Hopefully they start the stream a few minutes before NIN comes on... or even better, leave the stream up for a few days. I'm not recording because I'm on vacation with the equivalent of dial up internet.
