This looks an interesting project:
The Jazz research project seeks to extend the Eclipse (http://www.eclipse.org) software development environment with collaborative capabilities to support coordination, communication, and awareness among a small close-knit team of developers. This involves creating connections to server infrastructure for messaging, awareness, and source control, building hooks into the Eclipse development environment to supply awareness of the developers' interactions with source code and source control, and integrating user interfaces for communication and awareness within the Eclipse environment to provide unobtrusive access to in-context team information.
Let's hope that this Jazz does better than the earlier one from Lotus (which was bought by IBM):
Lotus Jazz was an office productivity suite for the Apple Macintosh, released in 1985 for $595, after the substantial success of Lotus 1-2-3 for the PC. It was a commercial failure due to its low quality and aggressive competition.
Ah yes, I remember it well....
