At the risk of making the proposal more complex, I wonder if it might be
better to support multiple checksum variants? The trade-off between code
length and recovery seems to be largely determined by the user's medium of
storage, which is likely to vary from person to person. I personally would
probably be interested in the 51 or even 102 character checksums variants.
