Complex matrices with UMFPACK

Just a quick question: are there any plans to support complex matrices with UMFPACK in the (relatively near) future? If not, how hard do you think it would be to extend the current integration of UMFPACK to deal with complex numbers? Many thanks for all your work on PETSc: it's proven a very useful and reliable tool over the years!
