Well, hello, I'm a carrara mac user and would be very interested in PFhoe too. I've been searching a little about it, and realised that Carrara import FBX files, a 3D format with time info, bones. I found a sample of skeleton bone (FBX file format). It was made to animate a character. I took infos for one bone and used it on a simple object. It seemed to move properly. You can imagine using a camera instead of this "simple object". PFhoe export FBX files to move a tracking camera. I don't have PFhoe, so can't see if it import properly in Carrara.
If I could have a PFhoe FBX file…
maybe you can sendme one :
