My recommended way to do this is to use PetscSection() to define the 
dofs over a DMDA. This currently works correctly in parallel
for vertex and cell dofs. The code for face dofs is in there, but I 
have never tested it. You have to use the 'next' branch because this
is experimental stuff.
Thanks Matt, I'll check this.
Do you have any info about PetscSection() (a presentation, tutorial, or 
whatever), or I should just use sources?
