Have you looked into CalendarServer[1]?

It's an open source implementation of a calendaring server using  
caldav and other goodies.  It is developed by the folks at Apple, but  
runs on lots of other platforms.  We use it at our office running on  
an Ubuntu box for shared calendaring support amongst all our staff. I  
did not do the install, but was told it's not difficult at all[2].

I'd be interested to know if you use CalendarServer or if you wind up  
finding another solution.

Good luck!
