Poser has been needing an overhaul since P5. (P4/PPP I actually liked - light, fast, and damned useable for what it did).

DAZ began building D|S back when Poser 5 was still in development, because EGISys (Curious Labs' parent company at the time) was coming up against some hard times, and there was some bad signs showing behind the scenes. DAZ built it for the same reason that any sane company would - to insure their own future.

Dunno about the featureset Poser should or shouldn't have offhand, but building an SDK is a bit more complex than simply releasing one.

The reason Poser's SDK costs so much is because you're getting a monster chunk of code with it. A normal SDK is a set of "Exposed" functions and classes, to allow you, the outside developer, to add functionality to the program. It will also include code that helps facilitate your plugging in to the app. In English, an SDK gives you stuff to make your program work with the program the SDK was written for - either as a plugin or an external application.

So... the Poser team would have to write an SDK first. Their likely response will be to point the typical small developer to their Python compatibility, and tell you to write for that (it would be like DAZ telling you that unless you had a lot of money, you're stuck with using the DAZ|Script for D|S).
