Very interesting. I hope I could join the review and testing. How do you think this would contribute to easing the port of Oracle PL/SQL procedures? Would the combination of orafce and this feature promote auto-translation of PL/SQL procedures? I'm curious what will be the major road blocks after adding the schema variable.
