Earlier, I posted about using mobile phones to convey emotional attachment, without using verbal communication. A while ago, I also posted about the possible use of mobiles as bio-feedback devices to attenuate stress through concious control of heart-rate variance.

I am now wondering if these two ideas can be connected. Is it possible to entrain one heartbeat with another through a bio-feedback loop involving two people?
