Hula Project Web calendar

Some time ago I wrote about an Ajax based web calendar. The same stuff is now implemented in the Hula Project ‘s web calendar. Check out this flash video and start drooling.
The Hula project is a free software/open source mail and calendar project announced by Novell. It is derived from an existing product by the same software house, called Netmail. Read more here.
It is definitely one of the most interesting new groupware projects, which might become a more serious Exchange alternative. I keep a close watch on that one.
