Definition: Google Wave is a platform, product, and protocol for creating live, social communication documents that can be edited by multiple users in near real-time. Google Wave's creators, Lars and Jens Rasmussen, thought of it as a modern reinvention of email.
Google is releasing the code for Google Wave as an open source project. As of this writing, Google Wave is in an invitation-only beta. Invitations are sent out to people who signed up on a waiting list, and those new users are given the ability to "nominate" other users.
When available, Google Wave will be located on the Web at wave.google.com.
