Star Trek type comms badges?

["Mark McCall" <lists@xxxxxxx>]

Vocera Communications Badge is a wearable device that weighs less than two
ounces and can easily be clipped to a shirt pocket or worn on a lanyard. It
enables instant two-way voice conversation without the need to remember a
phone number or manipulate a handset.

The Vocera Communications Badge is controlled using natural spoken
language.
To initiate a conversation with Jim and Mary, for example, the user would
simply say, "Get me Jim and Mary." In addition, when a live
conversation is
not necessary, text messages and alerts can be sent to the LCD screen on
the
Communications Badge.
