DMZ 1.7.1 (DataMapper OverZealous Edition)

[eluser]introvert[/eluser]
Hello.

I came to situation where I have to work with hierarchical data structures.
I thought of using nested sets approach instead of adjacency list.

Is there any info on how to easily implement it with DMZ? Has anyone already done that?

Would be cool to have model extension like:

Thanks for help.
