Ok, so I'll try and explain

I have built a simple "page builder" using nested Block Lists, and so far so good, I really like Block Lists!

At the the root of my site I have two nodes: the root of the site (homepage), and a "Data" node that has amoungst its children a doctype collection called "Packages" which I'm trying to access.

I have a doctype/page on which I'm trying to render the children of Packages. This is handled by a parent Block List that contains a nested Block List. What I'm trying to do is render those children via the nested Block Partial View, independent of the actual Block List editor UI. Except, I can't find anything to get a handle on. I think it's because the Model has by this point been converted into the type BlockListItem?

I'm hoping I can just inherit something to give me access to the root nodes, but I'll be jiggered if I can work out what!
