None, except that you need someone working on qtcurve

Everything is implemementable in QtCurve, though not via a simple text 
config file. So here also, you need someone to do it.

For breeze I reimported the needed parts of oxygen sources and started 
from scratch, mostly because a large fraction of the code from oxygen is 
overkill for Breeze's needs.
