The quality is nothing to write home about, which is likely due to a low bitrate used. My guess would be sub-300 kbit (see screengrab). Still, even in fullscreen and way better than the stamp sized experiences we used to see only a few years ago. How times have changed - here we have one of the biggest sporting events in the world streamed live, for free, over the net. I wish Sky would take some ideas from that.

But bitrates aside (they could be adjusted if wanted by the broadcaster), this is a huge event for live Flash video. After the Masters a few months ago I doubt that anyone still has any doubts about Flash as a viable and credible live streaming platform.
