A new Longhorn concept video has been released and is ready for download from the Longhorn Developer Center. The video weighs in at sizes of 6MB (320x240) and 14MB (640x480). Both videos are 4 minutes long. The video just demonstrates how "Telecommunications" is useful in Windows Longhorn. This video mainly focuses on Indigo and Avalon.

"Telecom companies have the opportunity to provide a crucial link in commercial Web Services. As corporate developers and end users assemble integrated suites of software exploiting telcos' network services, they can leverage telcos' core strengths in messaging, call-control, presence, location and billing – all via programmable Web Services. Telcos could help manage the wide variety of service choices and billing options that each desktop may choose individually. In this demo, Carter depicts a Longhorn call center application that coordinates internal and external Web Services to assist a stranded motorist."
