Check out Wil Wheaton's excellent post on the latest developments in the war on net radio. Good overview, with links to places where you can find out more. I imagine the tactics will get even sleazier as the major music labels continue to see their market positions get ever more dire. Of course, my interest in this is not only as a listener but also as a broadcaster. Depending on how things shake out, XDU could be forced to shut down its webstream. Which would suck.
