As the post makes clear, no one seems to know (or want to admit) just what is going on here. Hardly surprising, that. It's an embarassment for DRM and providers both.
This is one to watch, though. It's most likely to come to naught, but there is a chance we might at least get a glimpse into DRM policies at NBC, Microsoft and cable providers, who have to this point been quite successful in keeping them out of the spotlight.
