I had set up a private repo at a previous company around the time NPM was experiencing a lot of outages, and also to handle our private modules. It worked well when it worked well, but it did definitely require babysitting once a month or so. Totally the kind of thing you want to NOT just have one developer understand. What "npm-compatible" package did you end up going with? Assume you're not doing the couchdb mirror, which I really don't want to do again either, so I'm curious if this is a low-dependency sort of thing.
