does this allow for two way publishing? as in, are changes made to the online calendar synched back? can access to the published calendar be controller? i think these are necessary functions for “shared calendaring”. there are some tools which do this. HyperOffice is one. truly “shared” calendars are those to which access can be managed, and all those who have access to the shared should be able to make changes, which are then synched back to their Outlook accounts. hyperoffice does this.
