    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.
