Dear Paul,
the LDA+U + phonons has been implemented, in a version not yet 
publicly available. Simmetries and parallelization are still not there, 
but the implementation 
was extensively tested, and tests on calculated phonon dispersions against 
the experiments are currently being performed, on several materials. 
After, I hope-guess that the LDA+U in the linear response will be

To All in QE-Land:

Is there available, or under development, or planned, anywhere out there a
version of phonon.f90 and its supporting routines that accommodates the
output of an LDA+U scf calculation?

Cheers, -Paul
