Yes, LiveTeXmacs can run on USB stick as well as run on DVD! The last
LiveTeXmacs now is more flexible than ever: it is designed like lego-block
structure. You can activate/add new modules whenever you want to usethem.


The last version (1.4G) is focus on Python computing/visualization and
contains the following classified packages:

a) full slax linux system(200mb);
b) CAS: TeXmacs-1.0.7, Axiom2008, Scilab-5.0.1, octave, Maxima-5.16.13, etc;
c) Python-2.6:, scipy/numpy, visual Python, SageMath etc;
d) development environment: gcc-4.2.3 and gfortran etc;

Of course, only 200mb slax linux can run on several PC's or latop's with a
compact linux system. The left part of LiveTeXmacs (about 1.2G) enhances 
b),c) and d) above. 

The fantastic feature of LiveTeXmacs is that:

You can make the new package, deactivate old one and activate the last 
package.
   
For example, TeXmacs-1.0.7 in in the system. As CVS or the next version is
released, you can make the newest one and replace the old one just within
LiveTeXmacs. 


How to make a USB TeXmacs system

1.download liveTeXmacs from 

http://diffusion.cgu.edu.tw/ftp/modules/TeXmacs-CAS-python2.6-1.0.7.iso

burn it to dvd and copy all the files to your USB stick (2G or more, with w32
or xfs format).
 
2. enter boot directory and execute

 windows> bootinst d:           (where d: is assigned by Windows)
 or
 linux>  ./bootinst.sh /dev/sda1       ( where sda1 is the device recognized
by system)

3. If necessary, change the BIOS boot sequence to the USB STICK first.

4. To accelerate the boot speed, only basic system modules are activate at the
boot stage. Activate the CAS packages or other packages by the shell script
after booting:

> /mnt/sda1/activate.sh cas
or
> /mnt/sda1/activate.sh python
 
...

Press [Alt]+[Ctrl]+[Backsplace] to refresh screen and run the some shell
script in /etc/profile.d. The shortcuts will be displayed on the desktop.


Now it is bootable and workable with CAS. Here is a TeXmacs demo:

http://diffusion.cgu.edu.tw/ftp/texmacs/20081115.pdf

working on USB stick given in our lecture this semester (not well formated and
not completed). All the attendants in this class use USB Linux system!

Upgrade

1. (system upgrate) download the last slax linux iso from http://www.slax.org
and copy "boot" and "slax" to USB stick. Repeat the 1) and 2)
2. (packages upgrate) copy the new package to the USB and activate it.
3. (Make new package by yourself) activate the development tools:
   > /mnt/sda1/activate.sh gcc
   > tar xvfz src.tgz
   configure, make and make install, et voila.


I also made several packages (over 100) and put them in

Welcome to try it out and feel free to ask any questions.

Best wishes,
