I was thinking how of a good idea would be to use directional microphones to track people following their heart beat.
Each person heart beat must have a definite pattern in terms of sound and maybe that could be used to create a very pervasive surveillance system of all individuals, everywhere, all the time.
You may argue that vision is better suited. For that matter this might be what we would need:

Interesting that one could pick up passive X-Ray & Gamma sources.  Of course, there is also backscatter X-Rays.  It looks like most of these devices surround the item being imaged, but it should also work unidirectional.

Did you read about seeing around corners?

As far as the distinctive heartbeat, I'm seeing a few notes on the WWW.

http://www.dailymail.co.uk/sciencetech/article-2100566/Scientists-create-security-recognises-users-heartbeats.html

The system apparently requires and EKG, and thus a minimal of 2 points of physical contact with the system. 

I'm doubting you would get enough accuracy from a purely auditory system without direct contact to the body like a stethoscope.  The article doesn't seem to indicate whether it takes a single beat (about a second of contact), or if it requires multiple beats.  How accurate would it be with a million individuals?  A billion?

Are there places where a person naturally puts both hands for extended periods of time?  Escalator Railings?  Steering Wheels?

People can be identified by their gait ... http://abcnews.go.com/Technology/FutureTech/story?id=97779&page=1 [only about 90% accurate though]

The UK border control uses "heartbeat detection sheds" to detect people hidden inside a truck - which they then "clarify" to say it doesn't actually detect heartbeats....

I have heard of border control using doppler microwave radar to pick up the heartbeat of stowaways, but that doesn't work inside metal trucks...
