if you could help here, that would be great!

As far as I see, you've done more than most of us on l4-hurd ;-).
Seriously though, we are all very new to L4 hacking, so learning
by doing is not a shame at all. Just get your hands dirty by
writing some simple root tasks. It's not that difficult (yet).
The more you hack in the L4 environment, the easier things
will become. Sure, basic understanding of low-level programming
with C would be very useful, because the L4 APIs don't yet hide
the bit-manipulating stuff e.g. in IPCs etc. You'll need
C bit-manipulation skills to read the L4 headers as well ;-).

The hacking projects on the TODO list are more demanding (of course!),
but no-one is required to do them alone. We just need someone to start
writing a few files and place them in CVS. I'll hope (no, I _expect_)
that extensions and patches will quickly come in, as we have some
L4 and Mach/Hurd lurkers here on l4-hurd (right?).

I didn't read Zimmermann/Kraas yet. Could you briefly describe it?
Does it cover Mach 3.0 and higher? The only introductory book about
Mach that I know is Boykin et. al., which is very outdated, because
it covered Mach 2.5. Newbies to Mach had no choice but to grok
the canonical OSF/Opengroup docs (*sigh*). If Zimmermann/Kraas
is worth it, we could try to persuade their editor/publisher to provide
an english version? ;-).

_Every_ contribution is highly welcome!
