Zinc is a full screen browser for internet video. But that description doesn't really do the application justice. Basically, it allows you to watch internet video on your television screen using a remote control almost as easily as a keyboard and mouse. You know, a lot like Boxee. But there's one major thing setting Zinc apart from Boxee: Zinc is based on Firefox. And that's going to make it awfully hard for content partners to detect whether you're using Zinc or Firefox, which means it'll be a lot harder for companies like Hulu to ask Zeevee (the makers of Zinc) to block access.
