You can see a working calendar at http://demo.placid.be/agendas/1;manage

I can tell you our developer has tried out quite a lot of techniques  
to finally get to the point of getting the calendar as performant as  
it is right now. Our first route was using a table and  Droppables on  
every table cell, but it became slow as hell (even causing browser  
crashes on older computers). Now, the trick to making it performant  
is using a single element with a repeating background image to  
contain the calendar events, then use the coordinates to determine  
what's being done.
