   Yes. The new version of Frictionless: http://www.twinforces.com/frictionless/ 
  does this. I don't do iCal Event/Calendar syncing though, because I  
would need to hugely extend iCals Event model, which I've been avoiding.

  Yes.

   Do you have any kind of backtrace exception to start with?

   Meanwhile, add this to all your objects:

    def objectEnumerator
       print "Object Enumerator called\n"
    end

   I don't know why, but Sync Services likes to call this.

   Are you using CoreData as well? In Leopard, syncing when you start  
from a Core Data model is much simpler.
