I would second that CGNS would be a useful file format and about a year 
ago, I started writing some code to let Gmsh read/write CGNS files.  For 
various reasons, I never did finish it.  There is some code in the Gmsh 
repository to support CGNS and I might have some extra on my local 
machine.  I still intend to complete the work but find myself somewhat 
unreliable right now.  However, if someone else would like to further 
this effort, I would be more than happy to give a quick walk-through of 
the code that is in place.
