Our atom 330 servers push 100 Mbps and only hog 20% - 25% of two CPU cores.
The ram usage is about 200 Mb.
We stream flv and mp4 full scenes. Besides the bandwidth, the CPU and RAM usage is pretty much nothing. In fact, we have a paralel project to use all the unused CPU power on the bandwidth servers for mainsteam stuff.
This basically will pay for the bw bill and content by itself, so the tube will be 100% profit
