Hey, Cory, I'm not sure, but I think this post is off in the wording a bit. Oyez is not a file-sharing network. At least, I think that's a bit misleading. The project encompasses the encoding and release of the Supreme Court audio. But the Wired article goes onto say:

Anyone can download and share these files, provided they abide by the license from Creative Commons. The license permits the works to be shared as long as users attribute the work to the original source, use the work for non-commercial purposes and share any derivative works.

So these files can be shared, but I don't think Oyez provides the sharing infrastructure.
