Hi!

ADO is the better approach than something developed by self. See in downloads section my tests for custom algorithms of data transfer. Some are pretty good. Unfortunately, I had no time to continue improvement of these tests and add ADO there, however, I guess ADO ise better from the scalability point of view.
