Im a bit confused as to your answer..we need to know what the functions 
return and how the plugin writer would use them.

just suggesting how it could work.
 From reading the wiki seems like its more complex then it needs to be 
with multiple ways to get lists of objects.

having a generic way to loop through objecs (however its implimented) 
could be less work for you and provide a nicer interface IMHO.
