Speaking of Music Festival crowds, having worked at Love Parade a few years back where there were fatalities due to lack of crowd controls and at Tomorrowland last year, I was really impressed with the Sendrato bracelet that Tomorrowland use (http://sendrato.com/ ) which can be potentially used to determine densities of crowds in a particular area, and allow controls to be put in place before problems arise.
