One of the point on the APEX 4.2 SOD: http://www.oracle.com/technetwork/developer-tools/apex/application-express/apex-sod-087560.html
Application Deployment – Provide enhanced capabilities for packaging and distributing APEX applications to improve protection of intellectual property rights and ease customization.
My understanding is that the developer can export the application as "wrapped" so the end user / customer will not be able to see the design of the application.
Similar to to "locked" on the Packaged Application.
Does this features already exist on the current version or still missing ?
