It almost makes too much sense...
Every attendee at Coachella (X) has the option, at the time of the festival, and on the festival grounds only, can purchase one ticket for the following year's festival and that ticket would somehow be refundable, but non-transferable (matched to your ID or something). All the remaining tickets after the festival go on sale to the public in January of the following year.
It seems like this would prevent ticket brokers from purchasing large quantities of tickets for resale because it would shrink the pool of publicly available tickets. Tickets would be refundable, up until right before the fest, so it wouldn't hose people don't like the lineup or other plans come up (but would not be transferable to prevent scalping). Also, probably a majority of the tickets will still be available to the public. This would be just like a "carpool lane" or "verified ID" programs they have at airports to zip through security lines.
