At the risk of being flamed (and I am a Carrara fan), if we get Cycles PBR and instancing, we'll have something superior to Carrara anyway. Yes, it means using Blender to make stuff, but at least that's free (and much more capable than Carrara). My long standing dream was that DAZ would develop Carrara over Studio as it is a far better package, but that has not happened. I think a plug-in for Carrara would be a tiny drop the sales bucket for VWD's program (unfortunately), so IF it came to Poser wanting exclusive rights to the code (for a suitable fee, whatever VWD is happy with), then I would have to say that it would still be a good outcome. As has been stated here already, consider that the upcoming Poser version will make Reality redundant (although no doubt will still have users). Having this software properly integrated with Poser will ensure it lives on... Oh, if you can manage it VWD... try for royalties too...
