This is great! I've been half-barely-following IPFS development for a few years now but I think this is a salient use case that I could actually see myself using.
I think also with IPFS i can share files with peers pretty easily? It's nicer than uploading to a filesharing site, and easier than setting up a torrent.
So, what's next @sixtyfourbits? Is there a read-only wikipedia on ipfs yet?
edit: found it, but I think it's not searchable https://en.wikipedia-on-ipfs.org/wiki/
