We also need an IPFS source cache, not just binary cache. It would be an immutable source mirroring for all of our dependencies allowing reproducible builds from source (which is sometimes required as not all compiler flags are specified by default). I've had tons of problems buildings from source in Nix because upstream source urls break.
