Parallel distribution could still be a problem if we imagine a scenario 
in which a "flexible" DRM system allows derivatives to be created as 
long as they are kept under DRM control.

Imagine that work A is under a permissive license but has DRM applied 
and Work B is under a parallel distribution license and does not.

If we wish to combine work A with work B then we cannot, as we cannot 
create a derivative work without DRM applied in order to satisfy the 
parallel distribution clause.
