I agree that 2.4 is still quite OK. I'm a little concerned that dropping that
far back might store up some transition problems for the day we decide to
make the jump to Python 3.
On the other hand, I think gating features on RHEL5 might be
excessively cautious. According to [1], RHEL will red-zone within 30
days if it hasn't done so already ([1] says "Q4"). And RHEL6 (with
Python 2.6) has been shipping for two years.
I won't worry about Python 3 yet; in what timeframe did Python's
i18n/unicode support become usable? In 2.4, or 2.6?
