Hi, I have implemented such a feature in my custom online database app builder<http://creator.ifreetools.com> - iFreeTools Creator http://creator.ifreetools.com
After defining entities<http://help.creator.ifreetools.com/p/defining-entities-or-tables.html>and attributes<http://help.creator.ifreetools.com/p/defining-attributes-or-fields.html>online, one can proceed to define Auth Profiles<http://blogs.ifreetools.com/2010/12/access-control-up-to-field-level-now.html>specifying the access permissions and associate it to non-admin users. All metadata and the auth-profile information is cached and used within the app to render the forms and views for the users. You are welcome to try out iFreeTools Creator and as a fellow developer feel free to provide your feedback too. And of course, you can also use it for your database app, if it can meet your requirements. Single tenant deployments<http://help.creator.ifreetools.com/2011/06/deployment-options-single-tenant.html>over your own Google App Engine account starts at just $99/year for up to 25 users, going to a maximum of $297/year for unlimited users.
