To be free to do what I want, I have to be able to do it where (and how) I want. Modern machines are more than capable, so why are we relying on two intermediaries?
But locally-hosted software should always still be possible. I included something similar as one of the core tenets in the repo where I outline an idea for how we get things going: "After cloning this repository, it should be possible to start a development instance of bartok with a single command." Based on your feedback I think we should tweak this to emphasise local use, because there's a distinction between using software locally for development and using it locally because you're using it locally.
