OTOH all the data in Client is basiclaly POD, but i guess at some point it could be "a lot of copying", if you think it's worth it i can investigate some "less Q and more C++11-y stuff" and see if std::move or something works

  You take it, had a look and it's not as easy as i'd like, m_mapEntries makes it more difficult, and also the code kind of confuses me by m_entries containing pointers that seem to be extracted from the map itself? Maybe let's not touch this and just go with your simpler solution :D
