Festival radio. Device plugs into mixing desk USB and transmits to festival-goer’s devices
Listen to bands and artists from the comfort of your tent or campervan – or listen to the first 5 minutes of each set so you know if its worth making your way through the mud to the stage.

Would be good if we could set a camera up to stream the whole thing to the world, including the cricket and tug of war. Lol, then sell the downloads on your site.
Looks like you can stream fest videos easily enough, so even the lazy stay-at-homes could watch the ashes.
