Reuse Regions as a Component like Packages?

Question

Is there are way of making a region a single collection that can be treated like a reusable component, like that of a SQL Package? (Sort of Object Oriented Programming)
For example, I want to have a Region that display's a record's "CREATED_BY", "CREATE_DATE", "MODIFY_BY" and "MODIFY_DATE" fields. The region also has Buttons and Items inside it, to be included into the component.
These are used in different tables in the schema, so I was to reuse this Region (also, it uses a common package, that contain its different PL/SQL Code, that could manage the 'properties' and 'methods') in different pages that I nominate, preferably refering to a single definition. Should this definition change, it would be instantly changed in all associated pages as well.
I am not sure of the correct way of doing this. It does not seem Shorcuts in Shared Components will achieve this. Is there any Tutorial for this situation?
Thank you for your comments.

Ou, as I see such question is a common problem, I just start another topic with the same problem. I`ve tried to resolve problem by creating my own event that dispatch to listeners, and I`ve tried to add Listener to main app. Just in case it will such:
1. You create event: LoginCorrectEvent.
2. dispacth it.
3. main app listen to LoginCorrectEvent and make something.
You can check code in this topic http://forums.adobe.com/thread/700947?tstart=0
But I have problem that I haven`t instance to listen to, but you will have I suppose, so you can make event driven communication. Something like this:
var loginComp:LoginComponent = new LoginComponent();
loginComp.addEventListener(LoginCorrectEvent.LOGIN_CORRECT_EVENT, loginCorrectHandler);
it will be in you main app, and there you should define loginCorrectHandler - it will handle event.
