Yes, we have a project going on this. We're debugging the pre-alpha version
and will be migrating into libMesh and generalizing (beyond H1 conforming
elements) hopefully very soon. We will make a formal announcement on the
lists once it's more "beta" to help shake out the interface for the users.
It is being hooked into PETSc's DM infrastructure, so PETSc will be
required.
