What David said is correct (and how I currently deal with cylindrical coordinates). Nevertheless, while there are no formal plans, I've thought it would be nice to try and deal with alternative (to Cartesian) coordinate systems at the libMesh level. E.g. JxW comes premultiplied by r, curl/Laplacian/div/etc formulae have the right terms so that the same code could be used regardless of coordinate system, etc. Alas, it hasn't been high enough priority for me to spend any time thinking about it and proposing how to do it, e.g. whether it should be an FE type, etc.
That said, Peter, if you wanted to take a crack at it, I (and probably others) would be happy to give guidance.
