A system that tracks students through their mobile phones is among the new technologies being developed to help improve security at America's universities - something increasingly of concern since the tragic events at Virginia Tech in April 2007.

"The two hours it took for Virginia Tech officials to eMail students a warning about a gunman on campus last month have raised the question of how schools can get critical news out faster in a crisis--and how technology can help."

"Since 9/11, some security experts have pushed the idea that peer-to-peer alert systems that rely on openness and the crowd can save lives, particularly when centralized communications and decision-making break down. That argument is back in force following Monday's mass slayings of 32 people at Virginia Tech."
