Does anyone know if there are any API's exposed from the Windows Home Server? To be able to extend its functionality was the thought.
Yes. We you will see the Windows Home Server API documentation on MSDN soon. Please watch the Windows Home Server team blog for updates. http://blogs.technet.com/homeserver
The SDK went live with the Community Technology Preview (CTP) release that came out about two weeks ago. The API's and SDK docs are located on MSDN.
