Other Inkscapers might be of better help for your idea, but you can also set 'mid markers' for paths. Usually, you use start and end markers to create arrows and so on. But you also put them in evey node in the path. It's even possible to define your own custom mid-marker, but I believe it requires editing the SVG directly in a text-editor.
