@aboodman a lot of what you just outlined is possible because the CID implementation uses IPLD. IPLD is a data model that allows you to treat the entire universe of hash-linked data as a single information space. This is why you can have CIDs for non-IPFS content and can build tools like git-remote-ipld, which lets you add git repositories to IPFS and uses the git hash as the IPFS identifier for stuff within that repo – it’s resolving git content over IPFS protocol using the original git hashes. [see thread discussing git-remote-ipld
