I was thinking today that my digital set top box has a USB connection for a usb HDD to record & watch video from. I don't have a very large hdd but I was thinking it would be convienient if I could plug it into the computers usb slot & then be able to access the video files stored on my computer. I had a look on the web but most usb to usb conections are LAN simulations. I was wondering if anybody knew of aything that simulates a HDD. if not would this be a hard thing to implement?
