Perhaps in most cases yes. I do agree that having address pairs is the way to go. BUT, for my own unique situation it allows a completely transparent and cheat-proof method that shows that the purchaser of the ticket did in fact receive the winnings. There is no way I can do anything sneaky. It allows all purchases to go to the same address without worrying who paid. It's clean and simple. But, I'm probably going to be a minority who needs to do this.

I don't know if there is a solution that would work nice. I have a suspicion that it might not be worth it. If that's the case I'm content INFORMING my users the proper way to play BitLotto.
