This sounds very cool. I haven't needed XFEM before personally, but I
can imagine using it in the near future, e.g. for dealing properly with
crack tips.
Regarding (2): Are you thinking of adding a libMesh example that
implements transport of a signed distance function using DG? Or are you
thinking about adding core functionality related to this, e.g. a new
System subclass for handling this? (IIRC it's not just standard
advection problem in this context, since you need to renormalize after
every time-step to ensure it remains a distance function?)

Anyone out there doing anything with the extended finite element method?

I'm thinking adding core support in the DofMap and FiniteElement
classes might be a very useful thing, but curious if anyone had done
any work in his direction.
Providing (1) a mechanism for enriching our current finite element
bases and (2) a reference level-set discretization in the library for
the hyperbolic transport of a signed distance function (probably using
DG) could be a very valuable and reusable functionality, I think...
