A universal distributed file system that looks native on my system (thanks to FUSE) and caches content I access locally, while serving it securely to others, is interesting... assuming you can solve key problems like search, identity when you want it, privacy when you dont, and human memorable addressing... which afaict IPFS doesn't address. The "permanent web" on the other hand you can create using MHT archive files and BitTorrent magnet links. I struggle to get excited about that. Wake me up when someone figures out how to make apps that require seamless multi-user collaboration, like say distributed clones of HN, Facebook or Github.
