Can a QO-GFI or HOM-GFI breaker be used as a Sub feed breaker to feed a down stream panel and provide the GFI protection to the entire sub-fed panel?

Yes, BUT nuisance tripping may occur due to Leakage from ALL the load conductors between the GFI breaker and sub panel and the bussing in the sub panel.
