Cool hack. There are probably more efficient ways of handling entire files, but for small, public/cacheable lookups, DNS works great. I used to look up base64'd usernames to userid's via TXT RR's. The only downside is potential discoverability (even without axfr), but you could always run it privately. DNS is awesome. Distributed caching, sharding via zones, and UDP protocol with automatic upgrade to TCP for larger records, all at no additional cost.
