I was pleasantly surprised when I saw the announcement that  very happy with JBoss Portal and the eXo Portal becomming one project, two of the better FOSS portals joining forces… wow… JBoss Portal, to noones surprise already uses jBPM for workflow, but eXo in one of their modules does as well. Giving the user the choice of jBPM or Bonita. Both, in their latest releases (jbpm 4 will be out soon), having the PVM,  as a a basis. The latter, as you might know (but certainly do now), was developed with years of experience in field of workflow/bpm/… Great to see that great projects choose to to use great projects to become even greater (or am I exaggerating now ;-))
