The following is from the Missing Sync for Palm OS User's Guide:
MARK/SPACE CONTACTS AND CALENDARS
Until now, individuals who used Address Book and iCal to keep track of their personal information had to rely on Apple’s iSync Palm Conduit for sync functionality. Mark/Space now provides its own conduits to synchronize with Address Book, iCal Events and iCal Tasks. One major improvement over the older Apple conduit is the Mark/Space conduits’ ability to synchronize group and category information between Address Book/iCal and the applications on the device. Use the Mark/Space Contacts and Calendars Setup Assistant to choose your sync settings and preferences. For more information, refer to Chapter 5.
Note that due to limitations of Apple’s Sync Services engine, users must choose to either Synchronize or Overwrite handheld with desktop data. There is not an option for the handheld to overwrite the Mac.
The following is from the Missing Sync README
Synchronizing with iCal and Address Book, Microsoft Entourage, Palm Desktop and other PIM applications
The Missing Sync offers the flexibility to sync with different Personal Information Management (PIM) applications, like Apple's iCal and Address Book, Microsoft Entourage, Now-up-to-Date, Palm Desktop, and others. Some of these PIM applications have specific conduits that enable synchronization, and others share data with Apple's Sync services. The paragraph below is provided to help better understand what Sync Services is and how it works. The User Guide, which you can open from the Missing Sync Help menu, also provides helpful information on how to sync with iCal and Address Book, Microsoft Entourage, and the Palm Desktop software.
That is all the written stuff I could find in a few minutes of looking. Hopefully that will help.
