Quote - Python is for building plugins for Poser.  Yes, it's scripting but so is COFFEE in C4D (and you can build plugins with it).  Actually, Python is like Java - it runs bytecode.  You really don't want C++ or something like that. 

And it's very simple to wrap C/C++ code in a python library using SWIG. PoserPhysics was done that way, and in a similar fashion it shouldn't be very hard to take for example a 3rd party render engine that has a C++ SDK and turn it into a Poser Python plugin.
