Thanks for the hints. I'm already struggling with 
Tx_Extbase_Persistence_Mapper_DataMapper::getPreparedQuery() and see 
what happens as soon as I found out how to concatenate multiple 
statements via logicalAnd using the queryObject.

well, the doc comments say this is still a TODO, so it's a planned feature.
