I could have my HSX-109 or my RioCar (or whatever) streaming my collection to me while I mow the lawn. .... sure it wouldn't have great range, but it would cover my house (or within 300 feet of whereever I parked)... If it was cheap, this would be awesome. Maybe instead of accepting (or in addition to)memory cards, it would also accept CardBus cards so you could pop in your 802.11b or Bluetooth card at home and a NIC card while at work and tap into the lan... browseing content and songs...

Just thinking out loud.
