If we have coordinates of two nodes in 3d space, such as Stitie Space, we can find communication path(s) between such nodes easily using simple mathematics. (other paths can still exist).
We can define classes for such communication paths, and can index and manage them at Stitie Space.
If we have names associated with coordinates, we can find coordinates even if Stitie Machine at coordinates moves, for example: by calling carefully 'get' and 'set' accessors.
When we 'transfer' a Stitie Machine from one coordinate to another, we can find it's coordinates by Stitie Machine's name. This allows communication paths to adjust and reform dynamically after one or even both of it's end points move. This is what we'll call 'persistent connection' in context of this blog.
