The goal of self-contained packages is a good one. I love that this isolation is getting enforced through sandboxing on new platforms like iOS. Sort of off the main point, but I think Apple's thing just makes it easier for publishers to link into iTunes (those funny phobos.apple links), not rewrite song references it finds or anything like that. Custom protocol handlers like itms:// pop up some terrifying warnings by default and should probably be worked around. I'd consider plugins that rewrite content as bad software.
