I did when I still was SCAldera and although my NDAs don't allow me to go into details I can tell you that the AIX VM architecture is deeply tied into the segment architecture of the Power CPU and signicicantly different from any other UNIX variant. So porting code from AIX that touches anything VM related is a complete rewrite. Nice argumentation though, for everything but AIX it might actually have worked :)
