Incremental IDs work best, but if you want you can hash a UUID which will work for your use case:

% uuidgen

B14818B6-4219-43BD-82EF-8421EC1AFBCF

% echo "B14818B6-4219-43BD-82EF-8421EC1AFBCF" | shasum -a 256

Those urls are kind of ugly. If this helps at all, maybe I could create a public url id based off the incremental PK id's.
