Farenheit 9/11 is Downloadable

I didn't see this film, even though I wanted to. Now it is available for internet download here. The site in question claims to have Michael Moore's permission to distribute the movie for free, and that therefore this is legal -- I haven't followed up to see whether that first claim true, and I also don't know if the argument is valid -- that his permission is sufficient to make this legal, given studio rights, etc., but I'm taking the web site author at his word unless I have reason to do otherwise. The high-resolution WMV version is about a fifteen minute download on my high-speed connetion. I'm about halfway done with downloading it.
