I'm a happy Roku Soundbridge user. No, haven't hacked into them (yet), but they are reliable. And since I'm also a Netflix customer, this could be a nice win.
Now why didn't I hear about this from Netflix themselves? Hmm...
I'd still like to be able to view (easily) from Linux and not be forced to use Winblows for "Play Now" use. Perhaps that's in the pipeline; the Soundbridge product is a Linux box.
