The issue with apt install has more to do with a poor packaging mechanism on Debian's part rather than networking. Windows installers for once are actually superior in this regard since they generally provide an option to install for either the system or only the current user. Also, to provide multi-tenant hosting, you could just create some sort of root level reverse proxy (possibly Nginx or Apache) with some sort of registration system for domains. You just use the Host header to multiplex the system's port 80/443. For localhost stuff, I think you could set up something with DNS to be http://{username}.localhost http://{username}.localhost. It would be kind of an interesting idea to do as a happy medium between serverless and separate VMs.
