I know the Piwik recommendation gave some a reason to chuckle but I was dead serious. This initiative was promoted by Dropbox (who recently brought Condoleeza Rice on board) and Google (an ad company currently removing privacy-enhancing apps from their mobile marketplace) and so this group will need to distinguish themselves to appear credible.
It's that or be dismissed as just another iteration of Microsoft's 'embrace, extend, extinguish' plays.
