TDataset is the base class.
However, I think it is best you take one of the existing TDataset classes,
and write/use a TXMLExport class which simply converts any TDataset to XML.
There are plenty such components on Torry, they should compile easily with FPC.
As for the communication, the ICS or Indy components can be compiled with FPC,
that should give you your communication layer.
