I responded to those - but didn't get a subsequent response.

The state as I see it is...

- The PyQt4 version works at least as well as the current PyQt3 version.

- Issues can be resolved through bug reports and ripping off solutions from 
your C++ version (there shouldn't be anything that can be done in C++ that 
can't be done in Python). I'm happy to provide patches if and when required.

- An API based on the existing PyQt3 version will help porting.

- A Python wrapper of the C++ version will involve work to the VTK build 
system. If someone else were to pick this up I would happily provide the 
necessary wrapper.

The simplest approach is to apply the patch.
