Hello I was wondering about the possibility of creating a CUI mod like the one WorldEdit has? Its all fine and dandy the power of /ps visualize however my work flow in protecting my land would be greatly increased if there was a way i could walk into a field that i own and simply have it automatically visualized for me.

Is this at all possible? I recall your plugin visualizing through the client not the server. So it seems you already have the support for it.
