[PySide] Let's get serious for Pyside to support Qt5

Are there other Python projects or libraries that use dynamic binding to C++ libraries? It would be an interesting idea but part of the problem of calling C++ directly from Python is that there is no defined calling spec for C++ like there is for C so any calls that go through a C++ library need to be wrapped in a way for Python to call them. I believe, from reading what was decided in the history of PySide was they looked into packages like sip (what PyQt uses) and SWIG but decided that the footprint for the final binaries was too big and thus wrote shiboken.
