Building on Marcel’s idea, you could try this:
Do all of your coding in a Python node instead of using nodes directly. Or at least the important parts of the graph.
Store the Python code as a string on a website (access from multiple locations) or in a text file (local use only) placed on part of a local server which requires additional credentials to access.
Place a single Python from string node off the read file or web request node, and use some means of inputting the credentials to access the file/site.
If any of the bad monkey’s, or other powerhouse package managers ever do this with their work I will cry every day for the rest of my life.
