Little wonder, as I don't have a specific implementation, just a set of
fuzzy ideas.

The nodes are labeled with geodetic (presumably polar, as matter tends to
self-organize in hierarchical orbital assemblies) coordinates. You know
which coordinates your direct neighbours have (and maybe their neighbours,
if your wiring deviates too far from orthogonal).

The dumb approach would be just forward (probably fixed-sized) packets
through the link to the node with the coordinates geometrically nearer to
the target (here's your proximity metric, it's just an n-dimensional
Bresenham). Real world implementations would accomodate for
unorthogonality of realworld networks, and preferably use less loaded
