TP - Trace a line to closest particle

Hi guys, I'm currently working on a shot where I need some particles to draw a line between them and the closest particle to them. I've already worked this out, using a Psearch operator and an Iterator for the lines. The issue is that I need the particles to connect to the particle closer to itself and never break that link, even if a new particle comes closer, in wich case, it would create a new link between itself and the new closest particle, but all the old conections should remain.
I've attached an image with the general idea, I hope I made myself clear. Any ideas on how to solve this issue would be greatly appreciated

you can store nearest particles as references and then in every frame create lines of points (iterator node) between particle and all its references.
