We've done it several times now, and the volume of data transferred is the deciding factor. If the volume is low, you can write a simple Delphi program to do it (using the BatchMove widget). If the volume is high, try exporting text out of Oracle, then importing using the SQLS bulk loader (the moral equivalent of SQL*Loader). With truly large daily transfers -- say, >>100K records -- you'll probably find that it's faster to drop the SQLS indices and re-build them after each transfer.
We couldn't find a way to patch an ODBC client into SQLS to make the data transfer happen directly with no intermediate. This may be possible, though I doubt it.
