What's the connection between the two? (hybrids <--> PAW)

I think that phonon with PAW has been implemented and should be available at least in the CVS version, if not in the latest distribution.

Phonon with hybrids has not been implemented or is just on the way. Let's wait for a reply by Paolo or Stefano dG.
