The device serves a few purposes: you can use it to give all sorts of files to other machines in your home, or you could plug it into your HDTV or Blu-ray deck in order to stream PC-bound content right to your den. The goal here was to make other devices assume that this was just one giant flash drive, with gigabytes upon gigabytes of media right on the drive. So far as the receiving PC or set-top box knows, the IUM is just a stock flash drive with a capacity of your choosing. Just drop files over like you would from a standard USB key, and it shoots across the network to its final destination. Currently, it's not suggested that you use this to send files over the internet -- the lag in tunneling just makes for a poor user experience. The demo we witnessed (watching a Simpsons episode that was hosted on a nearby netbook) was remarkably smooth, with the user being able to skip ahead by minutes at a time with no visible lag. There's even the hope that the internals could one day be integrated into laptops in order to remove the need for an external dongle, but for now, you can expect a summertime release in the US and a sub-$150 price tag. So, you fixing to get your stream on, or what?
