um... are we talking about a widget that streams video into an object in an imvu room?
that is, something that can show the video like on a tv screen in a room, and it gets treated like a 3d object, moving as you move the viewpoint, getting larger, smaller, etc.?
or, are we talking about a static 2d overlay that floats over your view of an imvu room, like on a web page?
also, video and audio, or just video?
there are a number of youtube addons in the imvu store, but they seem to be mostly janky 2d overlays.
