there's an alpha-release interpreter based on cpython2.6 that has support for 2.6 extensions, & can automatically generate & import files using 2to3 (& pure python3.0 scripts as well). it consists of 3 files & is intended to coexist w/ an existing python2.6 installation

http://pypi.python.org/pypi/py3to2

enclosed is its patch summary against Python-2.6 (most of it deals w/ backporting 3.0 opcodes).

here's a test run of it (version 2008.11.23) importing most of Python2.6's standard library regenerated by 2to3:
