Bandwidth between nearby devices

Transfer data wirelessly from one device to another device in close proximity. A common operation, for example one person wants to share his or her media collection with someone else. Thinking for the future, a typical data transfer might be about 1 terabyte.

We are probably limited by the Nyquist frequency. For radio, this is to slow. But infrared, or free-space optical could work.

What is the maximum wireless bandwidth?
