- modifying a Live CD/DVD installation -- probably not the easiest to change on the fly or - get a big enough flash drive to hold a reasonalbly functional installation

Since you mention a live CD/DVD, I suppose you want a "run anywhere" installation. There have been a number of LG articles on this problem, for example:
LG 87 -- Sunil Thomas Thonikuzhiyil -- I Built a Custom Debian CD from Knoppix http://linuxgazette.net/87/sunil.html LG 113 -- Kapil Hari Paranjape -- Roll your Desktop into a USB stick/CD http://linuxgazette.net/113/kapil.htmlA different approach was also written up:
LG 140 -- Kapil Hari Paranjape -- Setting up an Encrypted Debian System http://linuxgazette.net/140/kapil.htmlTake a "standard" Debian installation which has the following additional characteristics:
- starts the vesa frame buffer at boot time - uses the vesa frame buffer for X - uses DHCP for configuring the network - uses LVM and/or disk labels in /etc/fstabThis kind of installation should work on 90% of hardware without additional configuration. (Modulo Wi-Fi).
Install this on a USB hard disk as suggested in my article in (LG #140) You can skip the encryption part if you like.
This will give you a run 90% of places installation with "permanence".

That's a reasonable distinction to make for theoretical purposes, certainly - but in the case of using a laptop to "drive" six displays and keyboards, one of the requirements is six video output connectors, one per monitor. I don't know of any laptops that have such a thing - no matter how many display buffers they have.

Now that you mention it, that might be very useful: a two-computer network for not much more than the price of one might be quite appealing to a number of people. E.g., you could essentially halve the amount of money necessary to set up a small network, as long as pairs of these "workstations" were close to each other. I wish I had the hardware and the leisure to experiment with that... maybe one of our readers who has the equipment and the enthusiasm will volunteer - and write an article about the process. Shouldn't be very difficult...

And now that you keep mentioning it, I've seen some drivers in the kernel's USB section that drive a VGA display via USB (one is for LCD display AFAIK). More than one keyboard and mouse might probably connected by using USB, too. This calls for some experiments and probably volunteers. ;)
Best, René.

I hope that our bait^H^H^H^Hencouragement - whichever flavor - works.
