D|S is not a "plugin" for Poser, it is a seperate application that over time will have more and more functionality added on to it via plug ins. At first, all it will be able to do is import .PZ3 files and render them with its brand spankin' new renderer. It has been said that the first version of D|S will be able to save renders, but not scene files. I think MallenLane said that, correct me if I'm wrong. Later versions will be able to save scene files as well, but when it is first released, it will just be a seperate renderer for Poser. As to whether or not it will be competition... at first, I think not, seeing as it will just be a kind of "add on" for Poser. However once they start releasing posing and animation plugins, yes, I think it will start giving Poser some serious competition. DAZ have also stated on their site that they intend to create a D|S specific file format, so I wouldn't be suprised if once D|S is fully up and running, that they stop making products for Poser, and start making them specifically for D|S (although Curious Labs could add in D|S file format functionality in a future release of Poser, just like D|S will have Poser file format fucntionality in addition to its own). Just my two cents. :-)
