Hi Jeremy - The IUser interface is not meant for extension in
Mosaic.What is the purpose of the extension? Maybe we can suggest some
other ways to achieve your goal.Note that you can assign roles and
permissions to users on the
server:http://help.adobe.com/en_US/LiveCycleMosaic/9.0/getStart/WSc07293f6c9641ff7600138e412411923524-8000.html#WSc07293f6c9641ff78e0fd85124160dc8b8-8000These
roles and permissions can be used to deliver certain tiles to certain
users, but the permissions are not exposed ...
