The $99 box from Roku that allows Netflix customers to watch videos on their televisions streamed over the Internet is all sold out, and there won't be any more shipped until at least July and possibly August. Which could be a deliberate strategy — underproduce the initial batch, sell them out, and look for the business press to bite on the hype. At least, that's what Scott Kirstner at Cinematech suggests. I just think that if Netflix has any shot at making this box ubiquitous, partnering with a company that can't sustain a supply line for six to eight weeks at a time isn't going to help. But then, such are the woes that have bedeviled all potential IPTV providers — thanks to the mysterious curse of the set-top box.
