Integration with the Views module

I would love to have the ability to create views showing the relationships (one or many).
I'm especially looking for the ability to show the whole chain:

parent 1
 - child 1
 - child 2
parent 2
 - child 3 (parent level 2)
 -  - child 4
 -  - child 5 (parent level 3)
 -  -  - child 6
 -  -  - child 7
parent 3

etc....

So, open ended views intergration, please :)

/thanks
