In my understanding, the TF will not discuss the provision of alternative Home Network technologies. Rather, it will discuss a W3C standard of home network API that an web application controls the device compliant with existing Home Network technologies.

It is preferable that the home network API is very generic and can apply any Home Network technologies, but the W3C solution has to specify a basic framework, such as, device discovery, for interoperability. I think that the UPnP industrial standard is a good starting point for the TF discussions, though any other Home Network technologies would be excluded for the discussion.

In terms of the phases like, "generic" and "also works with",  I supposed that any UPnP device-types and service-types should be supported by the API if the solution is based on UPnP.  If there are the requirements specific to a certain UPnP device-type, such as MediaServer and MediaRender,  it would be another discussion from the basic framework.

Thank you.
