so with sphinx the server doesn't have any accounts, there is no registration, nor login to the sphinx server. Users have a secret account_key. a user address a specific record by generating the record id as such:

id = h(user+host+server, h(dst_salt, account_key) )

where H is a keyed hash, and user, host and server are strings prefixed by their 16b length, and dst_salt is domain seperation tag.

users without the correct account key, will be unable to address an specific record. at all.
