python portable installation?

[luismi]

Hi,

I have searched the online manuals, faqs and forums, but i haven't
found a satisfactory explanation ... most probably my fault ;)

I have found 2 projects, one commercial and another free, that deal
with the installation and running of python code on portable/removable
devices, my questions are:
(1) Is this scenario not yet contemplated in the official releases,
and
(2) Why is such a big issue?

Will appreciate your comments,
Thanks in advance
