Video file w/ transparency info?!?! What to use?

My company is in early talks with a web-design company to create some 'video overlays' for their website. Essentially, they want a piece of video with a person talking that appears over a webpage. (The person walks out from the right side of the webpage and directly addresses the viewer.)
I know how to shoot the greenscreen footage, and I know how to pull the key in AE. What I don't know is how to provide them with a file that has transparency information that can be used with flash.
In video I would use a QT mov with an alpha channel, I'm not sure what sort of file I should use for the web, can FLV's have an alpha channel? What sort of file would be best for this?
