Nathan, i uploaded this part to github : https://github.com/ggouaillardet/ompi-svn-mirror/tree/flatten-datatype
you really need to check the last commit : https://github.com/ggouaillardet/ompi-svn-mirror/commit/a8d014c6f144fa573eeee2bdd25f8b6b05b07ea8 please consider this as experimental and poorly tested. that being said, this is only addition to existing code, so it does not break anything and could be pushed to the trunk.
