I seem to recall them doing motorsports with tons of live data including biometrics of some of the drivers. Heart rate, etc.

I spent the dotcom boom years working for a sports startup that was initially called Pangolin during it's prelaunch phase. I assumed that was a homage to Quokka. Pangolin rebranded itself as Sportal before launching it's consumer sites.
