Build an end-of-life 16MB Flash and/or Flash->thin client distro based on Debian, busybox and 2.6.8? with squashFS [1] [2]
Kernel
- strip almost everything, build in support for common USB ethernet and wifi dongles
Software
- base it on debian but see about building everything from sources optimized for i586-MMX (or whatever is best for the RISE MP6 and/or Winchip (2?)) to squeeze as much use out of the tiny processor as possible
- Blackbox or Windowmaker or Sawfish
- Konqueror can run without KDE but will require qt, kdelibs and kdebase. [3]
- Custom Debian Distributions
- apt-get install wajig -- to remove unused packages, purge-depend, etc
