Re: [development] Unique/Random IDs and drupal

Again, a driving use case is "two drupal sites that were founded independently of any knowledge of each other would like to merge their databases".

To me, two even more compelling use cases are: a) sharing global taxonomy vocabularies (the countries of the world each have globally unique ids shared across all sites) b) import/export. This is like the merge example from Ethan but perhaps a little more concrete in terms of what people are already doing. I could export my blog posts from one site and import them into another site and keep the id. c) global user ids. I always have the same user id on every Drupal site.
