Pushing data to external systems

I've created an InfoSpoke to stage data for an external application, using a DB table as the destination. Of course, BW will not let me write directly to a table outside of the BW RDBMS, so all it really does is de-normalize the data.

I've read that function module RSB_API_OHS_DEST_READ_DATA may be called from the remote system to pull the table contents out of BW, but I would much rather push it out from BW.

I've also seen a paper on how to push data from BW to XI, which is very interesting, but we don't have XI installed, and I was really looking for a simpler way.

Has anyone pushed data from BW using the Open Hub Service to an external application without using XI?
