I'm not very fond of being addressed in a condescending manner on my own forum, especially since I know what I'm talking about and only want to help.
I'd buy you several rounds of beer if I could but I can't just 'coz I'm too far away... Of course I didn't want to offend you. Sorry...
And plz notice that I know what I'm talking about too... (once again - numerous smiles there)
I've experienced some troubles with omitting \override\ usage for some types of resources so I've left those several COPY's there to be absolutely sure that that won't happen somewhere else at some specific conditions. It's not a big deal to wait some extra minutes during the installation.
But you're right about oggdec - that will add some reliability....
