You are wrong. Modern versions of Debian / Ubuntu are using Python 2.6.
My Ubuntu box has python3.0, too.

You are wrong again. We have an active discussion on the Python
developer mailinglist to integrate Unladen Swallow into py3k, see
http://jessenoller.com/2010/01/06/unladen-swallow-python-3s-best-feature/
. The other implementations have been planing Python 3.x support for
more than a year.

Python 3.x has builtin support for several aspects of OpenSSL. Other
important projects like Cython, lxml, some Postgres DBAs, Django,
mod_wsgi and many more have been ported to Python 3.x for more than a
year. In fact Graham has helped us to identify several issues in 3.0
beta while he was porting mod_wsgi to Python 3.0.

(Personally I neither see MySQL as mission critical nor as a powerful
RDBMS. Just try to combine foreign keys with triggers and you'll see
what I'm talking about. *scnr*)
