The venues have their calendars and capacities listed in the system. Marketing is direct to an established fan/follower base with known locations. Imagine if Kickstarter had the final destination of the funds, and customers of the products already locked into place before a fund-raise ever took place and thus known during configuration. Would make the entire lifecycle more deterministic.

I was thinking.. how can I raise money for 10 loaves of bread to distribute to the homeless? Well can't the bakeries at least be listed in the system too and shown during configuration?

But back to tickets - people can carry an inexpensive smartcard and use that to get in with readers. They could also print a qr code, or there could be a manual door list with id-checking as well. Blah, should I go on?
