Hi, I'm not Jesse, but I work with him, and maintain pyrax. I have only done some basic testing with 2.6, and everything appears to work correctly. I have also not used any of the new features of the 2.7.x versions of Python.

I would encourage you to try using pyrax with 2.6, and if you do run into any problems, please file an issue on GitHub and I will address it. We are ramping up our testing capabilities, and adding testing under 2.6.x is in the plans.
