That would be cool indeed.  Seems to be a missing feature.  BTW: I am normally 
using boost::python (which IIRC has been used to wrap Qt4 one, too), which is 
very comfortable (and may be used to wrap large libraries automatically using 
pyplusplus, incl. partial recompilations), but most probably more "bloated" 
than SIP.

However, on the C++-SIG list, Gustavo Carneiro announced his "pybindgen", 
which is supposed to be very lightweight (but maybe not advanced enough to 
wrap wx or Qt).

You can be sure that you are not the only one who would be very much 
interested in such statistics.
