 From a Plone perspective, Python 3 support is something that I don't see  
becoming important for maybe 5 years, so support for 3.2 is simply not an  
issue for us. Before Plone can consider a move to Python 3 we first need  
support in the libraries we depend on. For those libraries under active  
development it seems that compatibility with both 2.x and 3.x is the best  
way to go. Adding support for u'' to Python 3.x certainly looks like it  
would cut down the amount of work required for libraries like the Zope  
Toolkit which already use unicode extensively.
