An anonymous reader writes in with a CNet story about the record label-backed music company Lala, which claims to have invented "Network DRM." Lala has filed for a patent on moving DRM from a file wrapper, like Windows Media and FairPlay, to the server. Digital music veteran Michael Robertson has quotes from the patent application on his blog. (Here is the application.) Lala describes an invention that monitors every access, allows only authorized devices (so far there are none), blocks downloads, and can revoke content at the labels' request.
