Ok, sounds promising!

Just to get it straight:

  1) The old MeshFunction file format will not be supported in parallel
  2) To read a MeshFunction from file in parallel I need to convert 
     all my MeshFunctions to MeshValueCollections and store them. Then I use 
     that file to initiate a MeshFunction in parallel?

Doable!
