If you want to do package managers, your #1 priority should be Nix. Don't do something more popular where you help less, go with the thing that you can really provide the killer missing feature.

Nix + IPFS has been tried before, but what was missing is the Nix-side hierarchical content addressing of large data (not just plans). With the "intensional store" proposal, this should finally happen. Please push it along.

Data shouldn't be hashed like Nix's NARs, or IPFS's UnixFS for maximum interopt. Instead please go with git's model for all it's problems.

Thanks, hope someone can take me up on this because I'm up to my neck with other open source stuff already.
