you need all 3 dongles afaik. Rubber bands work fine. For feet trackers, you can also use some old socks you don't mind cutting up. Cut three loops of fabric on the top and slip the crenelations of the trackers through them, then you an just wear the sock with the tracker held to it.

I have all of my dongles just sitting on top of my computer right next to eachother. They don't need to be that spread out.
