Hey,

I'm wondering how to approach this problem:

I would like to create a custom node that allows users to create a handful of curves. Each time the user places a CV, I would like to run a bit of my own custom code (snapping CVs, checking distances, etc). Essentially I want the user to have a live preview how how the curves will look after my code is run.

Any ideas on how to approach this? I am pretty familiar with Python in Houdini and can jump into the HDK if necessary but I would prefer to stay in python if possible.
