Rivendell GPL radio automation software suite

Three weeks ago I reported about LiveSupport, an open radio automation software. Well, here is another platform I found: Rivendell. Doc Searls reports about it in his recent Linux Journal column:
Rivendell aims to be a complete radio broadcast automation solution, with facilities for the acquisition, management, scheduling and playout of audio content. As a robust, functionally complete digital audio system for broadcast radio applications, Rivendell uses industry standard components like the GNU/Linux Operating System, the AudioScience HPI Driver Architecture and the MySQL Database Engine. Rivendell is being developed under the GNU Public License.
This looks like a very professionnal an complete radio automation suite that’s already being used in commercial ventures. Intersetingly, Rivendell can be used as the basis for internet radio as well.
