PRISMIQ MediaPlayer
"The PRISMIQ MediaPlayer sits atop any television, stereo, or entertainment center and links to any computer via a home network or Ethernet connection. It eliminates the requirement to be physically present at the PC in order to experience digital movies, MP3 audio, and digital pictures. The PRISMIQ MediaPlayer also connects to the Internet through the home network for relaxed, TV-based web surfing, instant messaging, personalized TV-displayed news, and easy access to emerging next-generation broadband services."
Came across a semi-random reference to this product in one of the email newsletters I receive; don't know details but it looks like a potentially interesting alternative to the WXP Media Center approach.
