Where are the Resources Related to Ext.ux.Portal (Saving to Database)?

• Prettiest Example: http://taolin.fbk.eu/cake/taolin/ based on Taolin. Source code is at https://github.com/vad/taolin and is based on PostgresSQL. Ext.JS version used is 2.0.2
• A demo based on ext.js 2.3. Ext.ux.Portal is being extended to myPortalPanel. Source code is at http://code.google.com/p/itang-extportal/. However, didn't see any database being used. This has the best structure in using Ext.ux.Portal
• Another code spotted is at https://github.com/goldledoigt/Ext.ux.Portal. The design only involves in one table. Didn't see any acl being implemented with it. Not very sure the table is a master table or a table which stores the user preferences.
