Is it possible to run the web-player in windowless mode, and in particular with transparent background, similar to what wmode="transparent" does for flash?
Due to the Hardware accelerated rendering we use, this is more difficult for us then for software rendered plugins like Flash.
Currently, the only platform this is supported on is Safari 4 on Mac OS X 10.6. There, if you have ticked the "Use Alpha in Dashboard" checkbox in the Player settings, it will use the alpha channel of your game view for player transparency.
Sorry. As a matter of fact, is not possible right now :(
