The (re)design is fairly complete and implementation is underway, but there's a lot of work to be done. Help is welcome and there are a number of interesting things to be worked on (command processing, object persistence, threads and locking mechanisms, security, etc). The project page provides a link to the CVS repository.
If you're interested in helping please contact me, James A. Crippen. I'd love additional brains on the job. There's no mailing list yet but if enough people are interested I might make one.
