LOL@multiple access points around Nueberring, I'd like to see that.

But Cryinsham is dead on. You can't rely on the feed to make a recording (unless you have unlimited budget). On board hardware would have to record to HDD (I'd prefer SSD) then you could export and burn copies.

As far a as a live stream goes, for guests I assume, I would look at cellular technology. Mobile broadband would be much more reliable over the entire course, than wifi, even if you have multiple access points.
