- I don't think FNV-1A makes a great checksum. Move to SHA-something?
- The checksum is just in hexadecimal. If we could represent it more
efficiently, it'd be smaller. Maybe
base64, for great irony? - Auto-gzip the input?
- More characters!
- Accents, to push even more data into a character? Multiple accents? Might want to be careful of normalization, however.
