Yes.  That is actually the usual way to do things for quite a few years now.
What you are talking about is what we call a Python virtual environment.
see: http://iamzed.com/2009/05/07/a-primer-on-virtualenv/
http://simononsoftware.com/virtualenv-tutorial-part-2/
for an introduction to them.

It is common to have many of them for different purposes.  The bottom
line is that it lets you utterly ignore (at least from the python
point of view) any system packages you have on your machine.  Instead,
in a directory, you end up with exactly the tools, modules, etc
that you want for this project.

Works fine on a memory stick, too.

You don't have to worry about conflicts because you are, in effect, doing
a clean build from scratch for every project you have -- or indeed I
usually have many of them even with a single project so I can test that
my code works with different combinations of different versions of other
software.
