For what it's worth, I've known a couple of people who have gone off and done the meditation course through Vipassana, and all have heartily recommended it. Saying that, apparently the drop out rate of their course is something along the lines of 60-70%, most people do not have the discipline required to complete it. I personally haven't done the course so I can't comment directly. I would say though, that meditation is beneficial, and I'm sure there are proper scientific studies that attest to the benefits. Certainly the 'bio-feedback' movement is merely meditation techniques with some output you can discern, kind of like a server with monitoring.
