The ability to put Thuban on a media an run it from there is independent
from the "install_local" feature. This feature is only a comfort function
to copy the Thuban files to the system location where it usually would reside
in a GNU/Linux system. "install_local" allows you to run Thuban directly in
Of course you can produce a self-contain media running Thuban.
(My company Intevation has done this a few years ago.)
You need to put everything on that you need to run Thuban.
There are two general ways:
a) Complete operating system and Thuban. Works e.g. GNU/Linux
like a kanotix or morphix live-CDs. Needs all Thuban packages installed.
Putting it in will boot it.
b) Only the Thuban application (with all dependencies) e.g. ready to run
for several operating system like Windows, GNU/Linux.

It is possible to do this with Thuban.

I do not have experience with portablepython, so I can only guess.
My guess is that you at least need the wxWidget and other binary libraries,
but you can make it work. I cannot say how difficult it is, though, without
having tried myself.

GNU/Linux and Windows would need binary libraries for their specific variants
(e.g. Debian Etch, Ubuntu, RedHat, XP, Vista).
Thuban needs those libraries and they are not pure python.

I am not using Gmame myself, I have nothing against spreading knowledge
about this public list. :)
