EXACT!!!! This is my point!
We need  a standard portlet definition that states:

 "every portlet have to return 2 parameters:

   1. return code: if the portlet have to be rendered or not
   2. the portlet generated output 

"

With this agreement it will be easier for all us to wrap code around the 
portlet and to modify the generated html/dtml/zpt code.
