It seems from reading the MS site that it can be used to render when no GPU 
card is present, and then send the results over the network for remote 
viewing.  This is probably what the reviewer meant.

Yeh, the MS site also says that WARP is based on the reference rasteriser. 
Apparently it is designed to make full use of SSE4.1 and multiple cores.

Quadro FX1700 and E8500.
