Ask HN: Keep flash videos in fullscreen with dual monitors __on OS X__

Hey all. I just read the lifehacker article found here:

http://lifehacker.com/5419028/keep-flash-videos-in-full-screen-on-dual-monitors?skyline=true&s=i

On how to keep flash videos in fullscreen while using the other monitor to multitask. I've been dying for this functionality for quite some time however, the lifehacker article only describes a solution for windows.

Do any of you supremely intelligent people over here at Hacker News know of a solution?

Thanks for your time,

Greg
