I think at the moment this isn't wanted, I am keen to run on Python 3.4 (or at least 3.3). If somebody wants to come and help with this then we can merge it. I wont be testing it otherwise, so to say I support it would be a lie :)

So - unless somebody comes along and expresses an interest in this, we will stick with 3.3+ for now.

Hello,

I'm interested to use this library on my raspberry Pi, but only python 3.2 is available on raspbian. If this library can be ported on python 2.7 or 3.2, it helps me a lot.

Hi,

We are currently limited to Python 3.3 because we use the 'yield from' sytax introduced in Python 3.3.

This pull request does make most of it work and if you are interested in trying to update it to work with the current master I'd be happy to include Python 2 support.

OK, thanks. I will try.
