Gary Jin wrote calendar, Scott Meeks wrote acs-event, Ron Henderson wrote acs-calendar. Of those only Ron is still at AD.
I was in on all the design as I was originally porting events and we split calendar/events common functionallity into acs-event.
If I recall acs-event was complete, I quit AD before finishing events and Sarah Barwig took over. I can almost guarantee you that it was never finished as TCL went the way of Java. I don't think I have any of the old code and don't have an account on the AD LA office box anymore. If you guys can't find it I will try to get a hold of someone in the Pasadena office and see if it is still around.
