Ok, random scalper prevention scheme:

What's the difference between someone that wants to transfer their tickets from someone the know versus a scalper? Trust.

So when you buy a ticket you put, say, $1000, in escrow. The tickets have your name and ID on them. You can transfer the ticket to someone else. However, after the concert, the $1000 gets returned to the final person named on the ticket.

If the transfer is between trustworthy people, then the final ticket holder will give the money back to the original person.

There is no incentive to transfer money to the scalper, however. (Especially if scalping is illegal).

This doesn't eliminate scalping, but it significantly reduces it.

Critique?
