Today many distros make Python 3 as a default. While some existing Inkscape python 

extensions are not Python 3 compatible (or vice versa). So maybe I think its better to 

encourage extension developers to write code that support both Python 2 and 3 at 

somewhere on the website or wiki. For those existing scripts, we can either use 2to3 

to make them compatible or extend our support of Python interpreter to both Python2 

and Python3 (currently only "python" is supported in INX files). I prefer the former way,

though. What do you think?
