I've never said that it was impossible, just unwise. I believe that a userland approach offers no benefit over allowing the kernel to perform all meta-data operations. The end result of such an approach (given feature and robustness parity with the EMD solution) is a larger resident side, code duplication, and more complicated configuration/management interfaces. -- Justin
