Actually most Reg-Key schemes work exactly like that. The Name or email of the person buying is encoded in some way within the key, or via a reference in a database. Therefore the ID is tied uniquely to that customer. Of course you could mail around the program, but that won't help at all against being pirated, and might alienate some customers. Depending on tech-knowledge they'll either react confused or annoyed ;)
Note that there are some indy game sellers that work like that. If a registration scheme works that way, I expect it to also offer me a link to re-download at any time, even months or years later. Not all of the game portals do give more then one chance to download, a reason I do not buy from those anymore. Be aware that changing a single occuring string in your app to "hacked by l33t dude" is actually simpler then reverse engineering the registration code. That fact is also why Richard Gaskin is such a fan of putting registration code into several places that use various approaches to recheck for validity often. It's easy to change or remove one function that checks at startup, even when considering the work of decompiling. But it's much harder to go trough all the code and look wether it checks various stored registration keys or not.
