What is the fastest synchronization mechanism working on Windows CE? Maybe you know some good articles on this topic ...
Would ActiveSync be a good thing to check out and satisfy your question.
See here and here.
Even though you have mentioned CE, ActiveSync version 1.1 may do the trick?
Hope this helps, Best regards, Tom.
You may want to investigate the Sync framework. It can handle just about everything you can throw at it, depending on how "deep" you want to dive into the framework.
