Personnaly I think that implement strictly one of the STL container idiom 
would be nice.
Jonathan proposed sequence. Since it is quite simple and probably complete 
enough I think it is a reasonnable choice.

On the other hand, the fact that the element type is itself a container may be 
problematic.
So far I'm sure what would be the right thing.
