Adaptation of dynamically generated content

The focus of most current research directions in this area is based on a server/single-client relationship, whereby a client makes a request to a server for media, provides its contextual elements, and that media is processed and presented to the client. This arrangement avoids certain considerations when this relationship is not present, for example in server/multiple-client based systems (e.g. virtual environments) whereby each client is interacting with other clients, and the server is acting merely as a filtering and distribution platform; or for a client/client system (e.g. video conferencing) where two clients are interacting with each other directly. In both cases the concept of storing media in a database or file store, along with some kind of tagged description for the media, is no longer possible - and in essence while there might be certain elements stored on the server or even at the client, the media is either being generated dynamically (e.g. video conferencing) or as part of a mix (e.g. a virtual environment).
