Gail--you asked why advance seat assignments might be eliminated. No one element of security is infaliable. Having overlapping levels helps instill confidence. On the long haul I'm not sure how complete an aircraft inspection can be betwen flights. I think (with the schedule changes) airlines probably are looking forward to an excuse not to assign seats in advance. It also makes it harder for hijackers to make sure they are getting the seats they want.
Curbside check-in is another area open to debate. Since bags are checked with your name they have the ability to pull your luggage if you don't board the plane. It should be doable to add enough security so people can't deposit luggage directly on the belt or cart using counterfeit tags. The idea is to make it harder for people to do bad things.
