The problem of course is the use of Bridges.  If Any other program could use a Genesis figure with ALL the features it has in DS then there would be no need to have a bridge.  Genesis has been brought into Poser in the past and the DSON importer that DAZ made ran a mini-version of studio and translated Genesis to Poser.  It had to because Poser 9/2012 did not have sub-division as part of the Poser Program.  And yet Genesis in Poser 9 could be sub-divided.  If this was done by some magic of an arrangement of numbers inside the Genesis figures object file why did Poser not rearrange the object files for its figures?   A static doll is easy to bring in.  It is being able to do what the DS program does is what the difficultly is.  Since DAZ has not put their programs source code out in the public domain and that is where the magic of Genesis is located then it limits what can be done by other programs.
