To do this right at full res you will need approx 8Gb/min (based on the raw uncompressed output of Fraps at only 30fps, which uses about 1GB/min).
Of course maybe they are offering 320x240 4 colour 12fps.
No, they're going to use lossy compression to make the picture small enough to feasibly transfer in a short time period.
Oh yay, quality loss. We all love that, right? Yay cloud computing technology!
