Fullscreen FLV

I don't know how many of you have encountered this, but in recent past I have had many flash projects in which the client has requested fullscreen video. Many clients speak of the ability of Quicktime and Windows Media Video to natively go fullscreen from the web players.

Even though this is very possible to do using javascript, and a popup window, I long for the Flash Player be able to do the same thing natively.

This would be useful for FLV video, especially with the announced improvements to FLV in Maelstrom, so I remain hopeful that potentially Macromedia could facilitate this in some way that could not be abused.
