Great news this morning about the backend. I have created the build system inside Planner CVS module and now all the backend code lives in our CVS. As a good team, Micke has helped me in some dynamic loading issues and Richard has helped in coordinating the commit to the CVS. So now the code is in CVS waiting for you to test it! You only need evolution data server from CVS until next release. Be careful, the backend isn't complete and has some problems that will be solved.
