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).

>>i think what you mean is a local right. you need acl-rights on tt_news
and tt_news_cat. crud has an internal user table in wich is definded:
the pid(page,sysfolder), the fe-user, the acl-role from the user, and
the acl-group wich the user is member.so if you have an newsfolder wich
you assigned to the plugin, you can create on your newslisting page a
user acl-usertable entry with his aclgroup,pid and his aclrole. rights
for singlerecords works only if the user is the creator=owner of the
record. if you set the user as owner on the records, then it works,and
you can define multiple owners. with that conept you can create
usergroups with "local" rights for news, comments etc. with the backend
has crud nothing to do. did i understand you?

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

>>yes of course is all based on lib/div, what else ;-)

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

>>well your galerie has a database and so it has an TCA, and crud works!
and special for old plugins(pi_base) plugins is crud__marker.see last
post..

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?

>>both ways!

with all that its very
