[MOAB-dev] exchange entity sets

Hi all, I'd like to know if there is a way to communicate a whole entity set across processes. My actual goal is to create a layer of ghost "PARALLEL_PARTITION" entity sets instead of a layer of ghost cells. I know that it is possible to create an arbitrary extended layer of ghost cells but then I don't know how to recover the PARALLEL_PARTITION informations. I guess that exchange_owned_mesh/s(...) functions might help but I might be wrong. What's the purpose of these functions? Thanks for help. Lorenzo
