At PDC 2008, the Windows Home Server team has 2 breakout sessions. The video for the first session, "Developing Connected Home Applications and Services for Windows Home Server", is now available on Channel 9.
The full description of the session is:
Learn how to build applications and services deployed on Windows Home Server that power PCs and devices throughout a connected home. See an example home automation and energy management service, and watch the creation of an on-premises service that exposes HVAC, window shades, and lighting controls to all devices on the home network. Hear how to package the service as a Windows Home Server add-in, quickly create a configuration UI, deploy a PC application for controlling the service, and demonstrate control from other devices such as TVs and cell phones.
Tomorrow, there will be another video showcasing a development prototype of Windows Home Server and Live Mesh integration possibilities.
