Thanks for the clarification & info, Ben.

However, I wasn't able to find any link/dependency to the CPython 2.0 
license in current Jython.

http://www.jython.org/license.html is the same as the LICENSE.txt file 
included in the Jython distribution, and doesn't cite the CPython 2.0 
license, rather the JPython 1.1 license, which has the (questionable) 
choice of law clause, the (derided) acceptance ceremony, and the (???) 
revocability clause.

Jython distributions do include parts of the appropriate CPython library 
(currently 2.1, moving to 2.2), and so the LICENSE.txt should probably 
cite the appropriate CPython license (with which we comply by retaining 
PSF copyright notices and including brief descriptions of changes to the 
Python library).
