1. A method for virtual world and collaborative computing application integration, the method comprising: executing an intermediary as a single program unit in memory of a host server, the intermediary comprising both virtual world integration logic and also collaborative application integration logic and separately executing in the memory of the host server from both the virtual world and the collaborative application; establishing a communicative linkage between the virtual world and a collaborative application by way of the intermediary by coupling the virtual world integration logic of the separately executing intermediary to the virtual world and by coupling the collaborative application integration logic of the separately executing intermediary to the collaborative application; detecting in the collaborative application integration logic of the intermediary a posting in the collaborative application; and, creating by the virtual world integration logic of the intermediary an object with the posting in the virtual world, the creating and detecting providing for a two-way integration of the virtual world and the collaborative application, the two-way integration being achieved by additionally detecting by the virtual world integration logic of the intermediary a creation of an object in the virtual world including content and creating by the collaborative application integration logic in the intermediary a posting in the collaborative application with the content from the object in the virtual world.
