for some of my low end items (items that cost me under $15 or so) I dont mind shipping to an unconfirmed address. But there's no way I'm going to ship out an item that cost me a few hundred $ to some unconfirmed addy!
dunno if they have the opt-out link available yet or not, but off to see if it is.
edit - found it! to opt-out, go to My eBay, in the left-hand column click "Preferences" You will then find the opt-out option in the "Selling Preferences" section.
