        Sorry for being late on this, but my exams are going on.

        The python to java class unfortunately has not mapped the APIs
for some of the common python libraries. For example the gtk libs.
It would require extensive wrapping/mapping. My experience has been 
that Py=>Java works fine for command line apps. The DOM XML parser 
shows a far better performance. String operations too are faster. 
Since I started using python for GTK programs ( gladexml :-), I 
do not find the jython very useful. But the server (socket) programming
is fast using class files. Similarly I have been playing around SWIG for
plugging in native into python . It works fine for python, but Jython 
does not support SWIG.

        We would actually lose some performance, by the verification in
the SEE as well as in the runtime. But we would gain a lot of flexibility
as well as access to a larger programming community.
Happy Deepavali.
