Is there a Netflix client for Mac OS X yet? Video often comes with DRM which does nothing to stop the real pirates, but prevents legitimate -- paying! -- users from enjoying their content when, where, and how they want to enjoy it (which Hollywood doesn't care about -- they expect you to pay for every different way you watch it, over and over again, for the same content).
Unless Netflix brokered some deal with Apple/iTunes to wrap special versions in FairPlay (iTunes DRM), or provide a special App for an H.264 stream (the way YouTube does) tied in to some account login verification, we probably won't see Netflix for some time.
(Or ever, as it competes with Apple's own rental service).
