What about rights on rowsets - which means that I can define access 
control on a single record of a database table? This was one of the main 
problems I faced, because it's not even available in the Backend.
(For Example if you are running multiple instances of tt_news, every 
time you put your plugin on a page, a editors gets a list of all 
categories, not only the ones he should see in his sysfolder).

Does this mean, you implemented your own MVC Framework or is it based on 
lib/div?

What about controllers? Are you using another framework as a base-layer?

What about rendering of external plugins? I don't want to reimplement a 
gallery or a forum in my community extension, rather use existing ones - 
do you have a solution here?

Are these models generated on existing plugins? Or can I only access the 
data and not using the plugin's logic and rendering?

with all that its very
