Word can use a number of different types of data source, but they are all
either "file data sources", e.g. a .csv file, excel file, access .mdb, or
oledb/odbc data sources.

To use a "disconnected recordset" of any kind, you would have either to be
able to access it via an existing OLEDB provider/ODBC driver (I know of no
way to do this) or write your own OLEDB provider/ODBC driver (or, just
possibly, text converter) to do the job, and I'm not sure even that is
feasible unless you are able to pass a usable reference to the recordset you
want to use.

If you commit your dataset to (say) a SQLServer database, you should be able
to use an OLEDB or ODBC connection in OpenDataSource, but for OLEDB you will
need an external .odc file and for ODBC you will need an external DSN
(either "machine", or "file"). For OLEDB you may be able to create an empty
.odc file and provide all the necessary connection info. in the Connection
parameter of the OpenDataSource method.
