As some my notice in menu - Nimi Places 20110930 comes with server feature. Currently server can be used by web version of project: Nimi Places for Web 20110930. Server not only can store extension data, but also translates requests and responses between server and extension (like sharing supported by extension containers).

To enable server open menu, select other (three dots "...") click enable server. On first run You will be prompted with server settings panel.

To switch extension to use server mode, open its settings - go to basic, then storage and select server storage option. Server settings section should be now enabled. You can check server connection by pressing "Try connect" button.
