Not really the ultimate but I would buy a 2.4ghz (802.11b) wireless mp3 digital receiver (in beltpack)
or for that matter just a digital beltpack headphone (earbud) receiver - for good quality (perhaps a bit of a buffer) with a decent range, Like most Wireless Access Point's do have, so I can use the terrabyte on my home network, and when the kids have their MP3's blasting in their room I can still listen to my music or mow the lawn, this would also enable Internet Radio Stations --- Can somebody make one for me.

I have bought that many wireless headphones, the best one I bought was the Jensen Beltpack but even the range on that was pathetic, (anybody know a good 900mhz RF Linear Amplifier solution:-)
