It looks like this:

  <demostorage>
    <before base>
      before 2011-10-20 # or startup, or 2011-10-20T10:00 (UTC time)
      <zeoclient>
        server ...
        read-only true
        blob-dir ... # blob **cache** dir
        ...
      </zeoclient>
    </before>
    <filestorage changes>
      path ...
      blob-dir ...  # real blob dir
    </filestorage>
  </demostorage>

The before storage must be named "base" and the filestorage must be named "changes".
