Dockrillia linguiformis (Den. linguiforme) in a pot?

[Kiki]

I'm absolutely baffled as to the notion of growing this in a pot. How wide and shallow should it be to support the root system? And what dimensions would make it aesthetically pleasing? Since I've never mounted, potting or some other method would be a more comfortable option for me.

But if I wanted to mount a piece (I have a few), do I wrap the roots around the mount and secure it? Or just secure the piece to the mount?
