I love displacements, but they are part of the render system - like bump maps. But unlike Bump maps they aren't usually exportable. If I can't get it into Bryce it's not much use to me :-) Also be aware that all apps like ZBrush that use the REYES render system (this includes Mojoworld and Poser 5), displacements can cause holes in the mesh when rendered - especailly if the camera is too close.
