[pstricks] Package Recommendation based on Sketch

[Christian Häger]

Hello Everyone, 

This is a "soft" question. I want to convert the following sketch to a nice pstricks figure: https://dl.dropboxusercontent.com/u/42816591/sketch.JPG

Basically, I was wondering if you could give me some advice on which packages I should look into to efficiently draw this. Do I need to look into 3D packages or is this overkill? For example I am unsure about how to realize the node connection in 3D. Any help would be greatly appreciated! Thanks!
