Random idea: a serious business application for the twitter concept

Just thought of a possible serious business application for the twitter concept: keeping the management up to date with project proceedings. What's needed though, is an editor that is well integrated in tooling that is used by the end user anyway. The end user should not be forced to use some separate tool just for communicating proceedings. That's, in my opinion, the concept of the Information Workplace Concept: facilitating the end user with information and applications, adapted to his tasks, context and favorite tools.
