Yes, KSharedPtr, which requires the shared class to inherit from KShared, 
which is ugly and unacceptable in many use cases (For example, a class that 
inherits KShared can't be used by value any more). Frerich suggested a 
replacement a while back, which was rejected because it caused problems with 
the existing code in kdelibs relying on the behaviour of the old KSharedPtr ( 
a problem neither akonadi nor libsyndication have). I used Frerich's version 
until now by copying it into libsyndication - and I already had to patch it 
to make it work with Ms VS compilers when the shared type is an abstract 
class. So having every KDE lib and app shipping their own sharedptr can't be 
the solution - given that there is a well-tested version in boost becoming 
part of the standard soon.
(Note that also kdepim/akonadi uses boost::shared_ptr, libsyndication is 
merely following here (because I think it makes sense to have a widely used 
and tested shared_ptr implementation).
