Streamium is a consumer electronics product line from Philips which promises to bridge your PC movies, music and photos with rest of your house.
Like the previously mentioned HomePod, these devices work over WiFi and allow you to utilize your PC's multimedia content.
Philips had previously announced support for Rendezvous in such devices, hinting that it would provide seemless integration with your Mac. Phil Schiller also hinted at the coming of these devices in late 2002.
According to their FAQ, the 'PC-Link' enabling software to bridge the PC to the components does install on Mac OS 10 (though the download link is not presently available.)
