TBufDataset has 95% of all TClientDataset features, but lacks still the easy transport layer and delta application.

And the source code is available and for free. I have this code. There is a catch, because part of the code assumes units which are in the vglib sources, and those are not free.

It will not help with TBufDataset. It won't be easy to use cross-platform, because it has - partly - COM structures in it. My plan - as time permits - is to let Joost finish the TBufDataset. Then I will look at WST to create a transport layer. I currently use WST as transport layer to transmit data between a client and server, and it works as a charm.
