Future uses of Rendezvous
From the Apple Expo Press Release about Rendezvous, Philips CEO gives some examples of possible future devices:
"We both believe that consumers want devices throughout the home to talk to each other, so that, for example, the music stored in iTunes on your Mac can play through the Philips stereo system in your living room, or the photos stored in iPhoto can be displayed as a stunning slideshow on your Philips Flat TV. Rendezvous helps realize this dream. Philips is particularly pleased that Apple has adopted an open standard and architecture for Rendezvous, and we will support Rendezvous in future Philips products."
The timeframe Jobs gives for such devices is "sometime next year" from his Keynote.
