There is at least one small hassle (which can be a large hassle for the 
command-line jython user), which is readline support.

There is also the issue of embedding jython in a larger (Java) program (which 
I see as the main strength of jython since all Java classes become magically 
accessible and thus scriptable, etc) where the larger program contains GPLed

Hmm.  So given the very different concept of "linking" in Java:

1) If I use a set of GPLed .py modules in my jython script, am I combining 
the GPLed modules with my script, jython and/or the java interpreter? - which 
combination applies?

My interpretation here is script only.

2) If I use JNI wrappers to a C library that is GPLed, am I combining the 
GPLed library with my script, jython and/or the java interpreter?

My interpretation here is script *and* java interpreter, but I deeply fear 
that I am wrong.
