Baggins Bill (I think that's his user name...the one you see in the forums) is the one who wrote the library code, and I suspect it was his idea to host a web server within poser and communicate to poser through that. That allowed him to use a much simpler set of tools to develop the library code. So, on the user's end, we got a more sophisticated library system at the cost of some otherwise unnecessary memory and performance bloat. I wish they would drop it in future updates, but, at this point, I'm finding Studio's interface vastly superior, that it probably won't matter to me what's in the next version of Poser.
