that seems really powerful to me, and I hope to see some form of visual node representation beside the classic layer view some day... (yes the one in Blender is great ;-)

Today a motion compositor is sometimes the better tool to do a complex non destructive still composit because of things like the node editor or external referenced image sources.

Adobe After Effects for example is hardly criticized for its lack in true node editing.

--> A question about the planned new Gimp layer chain: Will we have a chain of layers with different operators applied to them and the option of linking child layers to parent layers and building groups for esay tranformation?

--> The input of such  a layer is stored in native resolution and processed by the layers trasnformation settings to match the composition? Can the input be externaly referenced? Will there be a resampling option to be able to reduce file size if I loaded a 24MP image but only want do design a web banner and don't want to save all the 24MP input dat with my composition?

I personally love the node editor of blender and would like to see something
like that in GIMP. The only problem with these node setups (like the one in
your screen shot) is that they are only graphs but no trees. And AFAIK GEGL
uses trees of nodes. Thus the cool things like several sources or forward
edges (think of a bumpmap on a layer which uses the same layer as source) are
not possible.

GEGLs XML serialization format is a tree, the data structure exposed
in the API is a fully general directed acyclic graph. As long as you
restrict the set of node types involved to: sources, sinks, filters
and composers with two input pads and one output pad, any graph can be
expressed as a tree with clones. In earlier incarnations (not in GEGL)
of the same tree serialization I also allowed embedding free-form
graphs as one of the nodes in the tree, thus more complex ops with
multiple inputs and outputs could be inserted there.
