PyQt doesn't have any problems with the proxy slot approach. SIP recognises 
special types that provide the additional information required to generate 
the correct code.  For example...

QAccel::connectItem(int id,const QObject *receiver,const char * member)

...is defined as...

QAccel::connectItem(int,SIP_RXOBJ_CON,SIP_SLOT_CON(int))
