Copyright & IP in Virtual Worlds
Raph Koster has a good post on the nature of copyright in virtual worlds up. Key points include the fact that virtual objects are entries in a database table (and thus not really protected from 'resale' by IP law) and the fact that the value in the iTunes store and other similar systems is the service they provide to customers (ease of finding music on iTunes, ease of finding draft partners on Magic: the Gathering Online, etc.) rather than the 'property' that they sell.
