Because the Nest is a very complicated piece of software, it is often unavailable (it is clearly stated by the terms of service, though, so nothing bad from this perspective).
However, many people wants to fetch pijul source using pijul, and in such case, they cannot. I think it could be a very good idea to provide a read-only HTTP remote, often updated (ideally sync with the nest, but at the same time implemented by another, dead simple software) as a fallback cloning remote for this particular use case.
What do you think, all?
Edit: I should have advertise I plan on implementing such a thing later this week.
