Support for zones?

[xtuc]

I would like to tag some of my cluster items as being part of a zone.

A zone is a subset of a subnet. For example two geographical locations sharing the same subnet or in my case VMs sharing the same network.

Graphically a zone would just be a rectangle with a colored border.

What do you think? Is is something that has a chance to be implemented?

PS: nmap won't be able to recognize them on its own.
