Project status
March 14, 2010
Unfortunately we have run into problems to get the project stable. Instead of becoming more reliable when more hosts are added, the reliability actually degraded. Until we have a very bright idea about how to solve this problem we will not be updating the project anymore. The project will remain active but it may be terminated if we cannot find a solution.
