Nathan,

In many applications, it could be a good thing to work with your own data
'set' until you have finished your work. And, definitely that can improve
the speed of the application.

Certainly there would be some technical and application design complexity,
but that should be hidden from the user. Vulnerability could potentially be
reduced if the synchronization process were performed with the correct
security design, etc. Lotus Notes has always had sychronization down, so it
is proven.
