Check if the current desktop is tiled or not

[napcok]

I like to have/write some indicator showing current desktop status: tiled or untiled.
It is possible to check that with some command?

I know it sounds like stupid idea, but I like to have zentile autostarted on 3-desktop (for example) and could be nice to have some status indicator maybe as an executor in tint2 panel.
So I need the way to check if current desktop is tiled or untiled.

Thanks for zentile :)
