[Trilinos-Users] Epetra_FEVector question

Hi - 

I'm migrating a finite element project from PETSc, and this code partitions on elements with shared degrees-of-freedom at nodes/faces on interprocessor boundaries.  Hence the ability to add local contributions to remote data structures is highly desired, which has me leaning to Epetra_FECrsMatrix and Epetra_FEVector...

I was browsing the Epetra documentation (http://trilinos.sandia.gov/packages/docs/r8.0/packages/epetra/doc/html/index.html#Epetra_formulations), 
and it states that the Epetra_FEVector is a specialization of Epetra_Vector. However, the inheritance graphs show that Epetra_FEVector is derived from Epetra_MultiVector.

Will this cause problems?  Is there someplace down the road where I will need an Epetra_Vector?  Should the _FEVector be derived from the _Vector?
