I've taken a couple of pictures but I'm not sure it comes across quite as bad as it looks in real life.
Normal or unacceptable?

The bit you refer to is called the hub. From around 2006 BMW's supplier for their non motorsport discs / hubs either changed or the manufacturing process changed for the worse.
You can try special paints and use lithium grease (as already advised) to keep the corrosion at bay.
