Sugar-server treats UUID values as unique identities of particular Sugar users, i.e., not unique identities of particular hardware that Sugar users run on (like OLPC XS does). If people need to keep access to their personal data, uploaded to the server, they need to keep private key, from {{Code|~/.sugar/default/owner.key}} file, and the UUID value, they got after registration on a server, as a an id or registration.
