Wirelessly Accessible USB Hard Drive?

Not exactly what you asked, but may give you an ides... I have the buffalo linkstation on my wireless network

) and store all my mp3's on there, so I can access them from any of the laptops/pda's etc, and just copy them to 1/2/4 GB jump drives for use on the car stereo (or the walkman/portable mp3 player type).. didn't seem to make any sense to get the cars to work with the wireless network, since if I'm in the car (or walking with the walkman type thing) I'm usually not home! That specific device has two USB ports (I have the 1 TB model), I use one for a network printer and the second for one of the el-cheapo 500 GB drives (use on the network for added storage, or hook it to each laptop for a way faster backup than wireless can do)... Haven't tried it to see if I can just use a jump drive off the linkstation, but they do make really nice jumpdrives with neck cords that are great for not home use...

A USB storage device can't be connected to two hosts at the same time. If your stereo can't function as a network device and file server, you'll have to unplug the USB device from it and connect it to something else whenever you want to update the contents.
