1. A computer-executable method for implementing a virtual business transaction between a first virtual world implemented on one or more first servers operatively coupled to a network and a second virtual world implemented on one or more second servers operatively coupled to the network, the method including: providing a searchable electronic catalog, through a clearance vault implemented on one or more third servers operatively coupled to the network, the searchable electronic catalog including one or more items each comprising a virtual good, a virtual service, a real good, or a real service; storing an object representation for each of the items in an identity repository database; establishing a set of transformation algorithms that are customized through a rule set; receiving a request specifying a copying, modifying, or reselling of an item selected from the items in the searchable electronic catalog; implementing the copying, modifying, or reselling of the item from the first virtual world to the second virtual world using the set of transformation algorithms; and implementing an exchange of virtual currency between the first virtual world and the second virtual worlds using the set of transformation algorithms, by directly crediting a first user of the first virtual world offering the item, and by directly charging a second user of the second virtual world purchasing the item.
