    we are currently preparing to port the module to Linux, NetBSD, MacOS X,
    and OpenBSD, as well as to 5.x. but, since the workforce is quite limited,
    it will take several months to finish the porting to 5.x. it should be
    easy, but, i realized that somebody has totally changed its procfs
    implementation, which the API of netnice relies upon. so, it will take
    a bit longer than it should be. if some of you might help us, that would
    be great.

    regarding the contribution to the mainstream FreeBSD, yes, we would love to.
    but, i'm a bit pessimistic about that option, simply because it looks too
    radical, at this point. maybe after we finish the porting to the major
    platforms, and the communities realize its scope and advantage, of having
    a multi-platform primitive for end-host oriented network control, we may
    start pursuing the option. but, that will be a future story. we still
    need to translate many documents for developers, and need to provide
    many netnice applications. so...

    yes, it currently supports just FB4.9, and it requires kernel patch,
    plus makeworld :-(

    since it is not a quick'n easy process, we have been asked to provide
    better (and easier) testing environment. so, we have just released a
    LiveCD version of Netnice/FreeBSD :-)

            http://www.netnice.org/download.html

    i'm planning to release a bit better FreeSBIE-based LiveCD with X + XFCE.
    if you want to see working apache + mod_netnice on the CD, i'll try to
    include it in the next release. please let me know if you have any request
    in that regard.

    thanks,
