Out of curiosity: Have you seen codes that actually do that?
What I would do, to make my life simple, is treated the whole scalar of 
derived type as a blob of memory and ignored what fields are actually inside, 
in what order, and with what padding. On homogeneous architectures doesn't 
this work just fine?
