Are there any restrictions placed on the mesh type for this? Structured/Unstructured? 

What about distribution of dofs? Like subdomain variables, etc.

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.
