Not a ProGet user here, but this definitely seems like a good idea.

What are the open-source / self-hosting options here? It gets a little messy with all the sub-dependencies, doesn't it?

If you only need NPM support we are very happy with npm-register[1]. I also heard good things about verdaccio[2].

Plus you also get private packages.
