Stumbled across details of an Intel initiative to provide the building block for a next-generation networked audio/video device. See:

and:

They have a reference implementation of the gizmo they call a "Digital Media Adaptor" which runs Linux on an Intel PXA210 processor:

These are available to potential OEMs ...
... but I wonder if they could be persuaded to donate one to an open-source initiative?
Anyone want to start something suitable? Reed?
