Thanks for the answers!
I've tested some other cases based on your suggestions and now have the
following situation:
- I create package classes which are derived from base classes, these will
hold non-pointer objects
- The packages split the objects into categories
- On the lowest level I have a list of shared_ptr<Package> - That way I
still have some kind of dynamic without wasting to much performance

I guess that's at least somehow what Robert suggested. The problem I have
with this is the following:
My application uses shared_ptr to hold most of the data. So if i want to
create a package I would have to copy the data first before I can put it
into the container within the package.
Am I right or have I missed some part of the idea?
