It works via BusyCal on the desktop. Each user must have it installed in order to see the published calendar that I publish from my desktop.

They can then view their ToDo actions in any of the following on their side:
iCal (notes can be modified and ToDos can be checked off)
mail (in the ToDo section)
BusyCal (required in order to see the LAN published calendar which is hosted on my machine)
or Anxiety (which I like because of it's minimal HUD)

we're setting up a machine with a static IP to run iCal server off of in hopes that we can omit the BusyCal step.

Wish us luck ;^)

cheers,
