I think Jython is exactly what we need. Of course it includes a runtime
system (interpreter) but this is necessary because Python's object model
is somewhat different from Java's (dynamic typing, inheritance).

jythonc allows you to compile a Python source to Java bytecode that you 
can plug into any other java application.

I think a real compiler with no runtime system necessary will only be 
possible with a statically typed Python, which is subject to the future.
