Using Vellum/SOp solvers with changing geometry

Yo smartipantses!

I'm just noodling with vellum for the first time. Has anyone had success with a vellum solver integrating with a SOp solver that is changing the topology?

In particular, I want the equivalent of a wire solver, so I'm using the hair constraint template. The wires are open polygons - growing by adding new points to the end every so often. I'd like the added edges to be added with the same bend and stretch constraints that the pre-existing edges have

Can anyone point me at a solution or example hip which runs a vellum solver with a SOp solver, where the latter is adding geometry throughout the simulation?

(The image shows the first point added just falling - with ineffective constraints. I've tried several variants with essentially similar results.)

Thanks!

clarifying, and typos

I finished this project up without using Vellum, which is a mild disappointment, but let me demonstrate how to use basic Trig to cheaply fake the influence of gravity.  Here's how it ended up:
