Write a script that will automatically import .ics to iCal

I can't for the life of me figure out how this iCal works! I've scoured the web and can't find a single solution! I'm trying to sync up my iCal on my home and work computers (the cheap way - without .mac). I've got the first half working, which is the work calendar publishes to icalx.com and I've got a script on the home computer that will get the calendar .ics file from icalx.com. But once I have the .ics, I can't figure out how to get it to programatically import into iCal.

Initially, I thought if I just overwrote the files in /Library/Calendar that it would work, but for some reason it's not - there must be more files somewhere else that it's reading from because as a test I deleted the whole Calendar folder and iCal still opened up with all the events and recreated the original folder. Anyway, I did a manual import of my .ics file that I downloaded from icalx.com and that worked perfectly, so I would like to figure out how to script it to run by itself! Anybody have any suggestions?

By the way, I'm using version 4.0.1 if that makes a difference.

I think you're trying to put much more effort into this than you really need. Why not use something like Google Calendar to sync calendars across Macs (instructions here).

I tried the google thing too, altho I may not have explored every possibility, but it didn't seem like I could have multiple calendars, like how I have "work" and "home" and "birthdays".

On the left hand side, there is a link under the list of calendars called "Add." You can use that add calendars.
