so you wanna send a email with the key and an image of the cd, which means u keep any legitamate form of ownership of it, but the person gives you computer parts in exchange. I'm sorry, that sounds really fishy to me.....given that in a few months you may decide, "oh, well, i'll use vista now" and install it. if microsoft finds out, who do you think they will believe is the owner of the software. ummm, prolly not the person who got it from you. pretty risky for the buyer, you should be sending the actual disk and the actual sticker to the person.
