On this specific matter, as far as I can tell, (and I'd be happy to be corrected if I'm wrong) Apple hasn't beaten them into submission at all.

If I want to buy music from another country, I need a separate account for that country, and I need either a credit card or an imported iTunes gift card from that country. Using multiple accounts on a single iPod, while now possible, isn't exactly fun, since I have to switch accounts to even get updates for free apps, much less make purchases. All this, of course, wouldn't be an issue if the same music was available in all regions.

Don't get me wrong, I give Apple credit where it's due in getting the RIAA and MPAA on board, but as far as I can tell, they haven't done anything to fight region-based market segmentation - not that anyone else really has.
