    Hm, how about a simple trick:

    you write a "remote resource access" filesystem and do

    mount -t remote_resourse -o access_control.conf 192.168.1.1 /mnt/server1

    then you "just" write a library to overload open, close, read, write,
    ioctl,... do

    export LD_PRELOAD=remote_libc.so

    and then

    mount /mnt/server1/hda1 /usr/local

    In /mnt/server1/ you could have interesting things like

    mouse0
    dsp0

    or even

    network0
    node0/cpu0
    node0/ram0

    Simple, sin't it?:-)

    Thanks
