The problem with lottery as auction is that it gives away the value of the domains, making the lottery tickets excessively like the kind you buy at the 7-11. One question I haven't seen addressed in auction proposals is what happens to the money. It could just go into ICANN's budget, but it seems to me the last thing the world needs is more money flowing into ICANN with no accountability. If it were up to me I'd dedicate the auction lucre to an outreach fund used for virtuous purposes like paying for plane tickets for network users in LDCs to go to the wacky places where ICANN has its meetings.
