User Interface Customization via land

You guys should have custom interfaces, not just "client skins". Let's say on your land you wanted to display a health bar? Or your altitude? Right on the screen? There would be something like that.

There should also be a llRequestPermissions for it. PERMISSION_INTERFACE, perhaps. The interface, scripted by the user, will load onto the screen. Perhaps you should accept .PNGs for quicker loading of them. The user can also cancel the interface by A: Leaving the Land or B: Releasing the interface?
The interface is manipulated via script. But NOT in an object. It can be in About Land, where an "Interface" tab would be.
Also, there should be buttons that the user can make via script. Something like llSetButton(string texture, integer x, integer y, integer length, integer height) for example. And when the button is clicked, it can return an integer that the user can declare, for example if button 3 is clicked then stuff happens if a variable is 3.......Or something.

With that feature, we can add lifebars, or HP Bars for RPGs, or stuff. That way we can really enjoy our games, and it would be an interesting asset to in-world game developers.
