The specification explores a provider-agnostic and product-agnostic implementation@ and will consider two primary aspects of the telepresence service that are detailed here by the examination of use cases deployed today and those resulting in the application of ""the cloud"" and other aspects of business and technology architecture guiding service evolution in the future. First@ a description of the telepresence service is provided. Second@ a more detailed description of the two key aspects of the telepresence service is provided.
