Oh, this reminds me of a Chrome extension I wrote to distribute Web content (images, html, js, anything) over DNS: https://blog.zorinaq.com/cdn53-a-super-distributed-cdn/ It implements the fake TLD .cdn53: when visiting http://zorinaq.com.cdn53 the extension intercepts the request, sends a DNS query for the TXT record for "_cdn53.zorinaq.com" and the response contains the HTML content, or any content, and it can be up to ~65 kb in size. It's super-distributed as it will naturally be cached by all DNS resolvers worldwide that hit the domain...
