[TYPO3-mvc] How to extend a model class from within another extension?

I think that's what was also planned for singleTable inheritance, which 
btw. could be implemented in the same go as it should need changes in 
the same areas.

I'm also far from knowing the anatomy of Extbase, but the responsible 
class/object building the objects you get handed over is the dataMapper 
(Tx_Extbase_Persistence_Mapper_DataMapper) and especially the method 
"mapSingleRow" (including it's sub processes). So you might want to 
start there.
