It's an interesting piece of hardware and works quite well. I've put together a review of the little silver box and have included some info on its architecture and the communication protocols it uses."
The reciever requires that you have a windows computer running to push files to it via http. There are 2 projects I could find that allow you to stream to the Dell Reciver from your linux server: http://sourceforge.net/projects/das/ and http://www.mock.com/receiver/
