I am not a lawyer, but there are essentially no limits to what someone can do once they've purchased something. If it's a service, then we have control, but physical objects become theirs. This is why record and video game companies get so twisted up about used media, etc. If they could stop it, they damn sure would.

Ebay can (and does?) have policies about selling things that aren't in your possession, but even if we could or did have something like that of our own, it wouldn't be enforceable.
