RE: trading private keys with somebody:  theoretically you could, but that's not typical bitcoin usage and the current bitcoin client makes it hard to do. @p{par}

Practically speaking, if Bitcoin did have a feature to state: @p{brk}
 "On THIS date somebody using the identifier @p{lt}@p{(link}foo@bar.com@p{link)}@s{gt} controlled THIS public/private keypair" @p{par}

... that would just inspire the smarter bad guys to send stolen coins to new private keys before spending them. @p{par}

I can imagine a black market forming where dumber bad guys sell stolen wallet.dat files (at a discount) to smarter bad guys (or just plain greedy people who don't bother to ask where the wallet came from), who mix up the coins in them and then sell them. @p{brk}
