We had a brief discussion about Nedelec elements (which are curl-conforming, used for Maxwell's equations) recently, and it wasn't too pessimistic http://www.mail-archive.com/[email protected]/msg02671.html Unfortunately no progress yet on Nedelec, but it would be fantastic to add vector-valued elements to libMesh.
