yes.  therefore i've thought of keeping the routing stuff left on the
kernel side and the scheduler stuff into the user-space using a
high-resolution timer.  the merit of this way is that you don't need
a root-priv. server for routing.

also, the event-packet communication should be improved e.g. via
mmap, etc.

yes.  i'd love to have a nice looking mixer.

yep.

hehe :)
in fact, there are many drivers holding a big static boot-image,
such as nm256, ymfpci, maestro3, etc.  they can diet, too.

agreed.  for example, mpu401-uart may use them well.
