CPython vs. Jython/JPython

[D-Man]

Hi.

This isn't to start a flame war, but to clarify some confusion I have.

I am wondering why there are two separate python interpreters being developed (the one in C, the other in Java).  Wouldn't it be more productive if both teams worked together on one interpreter?  Another thought I had was that it would be easier to make python cross-platform if it was written in Java and let the Java developers worry about the C-level platform dependencies.  Isn't it also possible to write Java extensions in C?  (read: ... python extensions in C (using the Java interpreter))

I thank all in advance for your insight into this matter.
