Nebulus, IPFS-Less IPFS. Take advantage of the IPFS content addressable file system WITHOUT publishing everything to the public IPFS network. With Nebulus, you can use IPFS privately and offline, and don't need to constantly run an IPFS node. Nebulus is a "Virtual IPFS", emulating IPFS locally by maintaining a tree of symbolic links generated by calculating the IPFS hashes offline, without connecting to the IPFS network. The virtual file system can then be selectively synchronized with the public IPFS network whenever needed.
