2to3 is intended to be run automatically for each release.  You would
not maintain two versions.

Byte literals are available in Python 2.6.  As far as I'm concerend I
don't see a real reason to port to Python 3 at the moment.  We should
rather get our stuff ready that once Python 2.6 is the standard the
porting becomes as simple as possible.  Supporting Python 2.4, 2.5, 2.6
and 3.x is a very complex task that does not work for every library (due
to changed APIs for example).

We cannot fight on too many fronts at the same time.  This thread is
about unicode and encodings, not about Python 3 syntax.  2to3 tackles
the latter, if it does not work for you, consider writing that to the
porting mailinglist.
