Google has now decided to package the software in a form that will allow organisations to host their own waves, although it will not have the full functionality of Google Wave.
The so-called Wave in a Box will be based on the existing open source code and include a server and a web client. Features will include threaded conversations, support for importing data from Google Wave, and the ability to federate with other Wave in a Box instances.
A number of vendors are already working on wave technology and more specifically the Wave Federation Protocol, including SAP, Novell and ProcessOne. In addition, various open source projects are incorporating wave features.
Google will continue to operate the service at wave.google.com at least until the end of 2010.
