Knoppix should try and support ADSL modems, both USB and ethernet. This is specially important as with Debians apt-get we can install all we want and keep us updated.
OK It is best known as a LIVE_CD, but many are using this as a way to install Debian - as the original Debian install is laborious.

Next on knoppix wish list is to build our ISO online by adding the software we need from a list to the ISO and THEN downloading - customization on -line :P
