Requiring ethereal/wire shark is nuts, so yes, let's set that aside.  As I
said, DSL, KioskCD, Puppy or Thinstation meet this.  There are others.  Many
others.  Basically most LiveCDs out there unless they are targetted at
rescue/repair or security in which case they mostly go directly to a cmd
line.

I assume you want to configure the LiveCD with a browser?  Or are you
talking about controlling where the users/websurfer goes?  Speak English in
complete, non-complex sentences.  Any LiveCD is going to require a bit of
finesse to customize.  It is not something that anybody can just sit down
and do.  Some stuff I learned in 5 minutes, other stuff I still can't do
yet.  Some is just too much a pain in the ass or I don't have enough room
for an uncompressed build or I don't have enough time strung together in one
place.  To really fully customize anything above the DSL, ThinStation or
KioskCD, you must work with an uncompressed filesystem and understand how to
chroot into that environment.  You may have to reenable apt and dpkg and
manually restore some files, kernel headers, do some compiling, restore
/etc/skel all kinds of things.  How much time and dedication do you have?

If you were in control of the gateway/router or proxy you could  have
infinite control of where someone goes, if that is what you are talking
about.   They go into this on the KioskCD site, and a bit  on ThinStation.
But you can proxy, cache, firewall, route, whatever how you want if there
are multiple clients and it is worth it to you.

A bit more functionality- this gets a bit harder to decide, Spell

DSL, Puppy, KiosCD you must use online doc creation (I have this with Google
and there are others I can recommend.)  ThinStation if you go thru the first
link on ThinStation-o-Matic (TSoM) you can add text editors and spell
checkers.  If it is not in the TSoM app list you must build it yourself and
add it.   Basically, most LiveCDs targetted at a desktop user, but you keep
mentioning minimal system hardware, so my recommendations stand.

DSL, Puppy, Thinstation all have audio support, KioskCD is supposed to.
Thinstation you must add in for which cards you want to auto detect, same
with  NICs.  I didn't  test audio on  KioskCD, it would only be for online
videos and system noises though.  I'll try to test and report back.  One
customization I plan for KiosKCD is update Flash to ver. 9 and add the
mplayer browser plugin, but if you add the codecs, then you can't
redistribute.   DSL has a VOIP client and I bet Puppy has one too by now.  I
may have seen on on the TSoM, but I wasn't looking for it, nor do I use
it.   Good luck with that USB VOIP thingie.  You will probably have to
custom compile a driver for whichever distro you put it on.

All of my scenarios are to pick brains for getting such projects

I recommend you somehow get MagicISO on Windows.  It is by far, the best ISO
editor I've used.  I can drag and drop and delete/add files to and from a CD
ISO file.  I can also replace or add scripts, batch files, .dsl, .unc, .uci
files, etc.  I can also change the boot .img file or extract the one that is
used in the ISO.  There is NO program for Linux that can do even half of
this.  Kiso attempts it, but it deleted several .iso files on me and never
saved the newly created files when I used it.  It is a good start, but not
there yet.  You can do some of the customizing with this tool, infact most
of what you want to do, you can do in Windows XP or 2000, but if you want to
compile anything, you need a working Linux environment and some space.  Some
of the DSL compiling can be done with a Knoppix LiveCD, but you must find
out which specific version has the kernel you need.  It used to be Knoppix
3.4 or 3.6, since those still had teh 2.4 kernel in use on DSL.   Check the
forum and wiki for details, the forums are a big help.  There are detailed
rebuild and customizing instructions on all the distro sites I've mentioned,
some more than others.  Not nearly enough on the KioskCD site.

Anyway, good luck.  Bring your customs into the LUG meeting for people to
try.
