OK, as my dbus is now working, let's come back to generics.
I see two possibilities for things like QLists and QPairs etc...
We could parse those classes with Kalyptus and work with them like with any 
other class, when we request an element via QLists.At() it would probably get 
marshalled the normal way - that would not require a huge change in the 
marshalling functions - I think we could even just delete the ValueList 
The other possibility would be to create our own Lists<T>, but it would be 
quite difficult to marshall from a C++-QList to a C#-List<T>.

I would prefer to just parse the Qt stuff with kalyptus and nothing more. We 
can then add some functions for interopability with C#, e.g. to cast a QList 
to an ArrayList and vice versa, so it is easier to use other libraries for 
Well, that's my opinion.
Do you already have some code?
