Calendar that networks...

I need to find a calendar that is like ical, but can publish to a network and be viewed by all connected macs, preferably, this app would auto update, so that when a change is made to the master calendar, it changes automatically for all to see the updates. Ive looked and cant find anything, any ideas?

Does it have to be a closed network? If not, you can publish iCal to .Mac or any webdav capable server for others to view. And you can set it to autoupdate whenever a change is made.

yup, closed network. I tried publishing ical, didnt work.

For an open network you could Mobile Me. That your sync your address book with other mac systems..right now it cost 99$/year and a free trial, mabey that will work

good luck
