A new project is born
So far I only commited the first bunch of files to SVN. Current codebase is fully functional in SQL Server.
As soon as the MySQL DDL script will be ready I plan to package a first release and make it available for download. In the meantime, if you are really looking forward to this, code can be downloaded from SVN.

BTW Sorry for answering so late, I haven't got any notification about your comment
Kinky Calendar isn't CFC based, so it's much harder to extend. Among other things, it doesn't supports scheduled publishing, images, attachments and skins. Ben has done a good job, but I believe what I am doing here is somewhat broader in scope.
You may give it a try now, or wait until I'll have the first build available, it's going to be a matter of days
