folder is a node but what about permissions?

Issue Summary

Hi i'm using zina and i have installed the dev versions to test the node feature.
Everithing works well after "synchronize database" and "populate database" in zina admin page.
Now my folders are node,this is great but;

It would be apreciated if there was "albums" and "artists" node.Not a must have but it will be cool.

My site is a "user oriented" site so users cant own their personal folder and upload what they want in it.
So i was thinking that if folders were nodes,users could own their nodes and modify it within zina module.
i explain myself,i would like users to do what i'm able to do as admin while browsing the site (modify bio or songs lyrics for example).

Is it possible?
