There will be a need to rotate client passwords. This design allows the
server to accept both old and new passwords during transition. Then, the
clients can be upgraded without interruption.

A user name may reduce the number of SHA1 comparisons (since we'll be able
to terminate the search earlier). Currently we don't have any other
access restrictions or logging that would benefit from a user name. Do
you foresee a need for any user-based authorization mechanisms?
Do you foresee a need for a large number of secrets?
