This is about supporting multiple applications which have a different CLASSPATH, essentially giving everyone their individual namespace.

I have a shell scripting based implementation which may better explain what I am proposing.

Suppose we have two applications: a and b.

$ ls -R *
a:
a.py  setclasspath.sh

b:
b.py  setclasspath.sh


In linux you can specify the interpreter, for example you can start a.py with
#!/usr/bin/env jython

which is awfully convenient, since you can then run you jython script by simply calling it:
$ ./a.py

The attached 'runjython' script acts like the jython interpreter, but will first call setclasspath.sh, setting the classpath for the current application.

This of course only works on linux, but demonstrates the aim of having separate 'classpath namespaces'. It also combines very nicely with IPython.
