Hello!

my suggestion is to use an openmosix patched kernel instead of a standard one, to make possible using a group of interconnected knoppix computers to work faster by joining their resources. At least older computers will become more useful if there were another faster knoppix computers in its own LAN, giving them 'a hand', it will be great to build a fast cluster to play with it, or using the laptop and the desktop computer to process together a complex task from time to time, etc.
cheers
