You will still be using the same VWD software you are using right now. The DS Bridge is only a way for us to interact with VWD (send to, return from) with some small differences in how Poser, and DS handle returned animations and poses. I like using DS more than using Poser, but I use both, so I will continue to use both, the DS Bridge (beta testing for now), and default VWD with Poser. Long live VWD!

I don't have the answer to that question, but I do know there has been talk of it before. Hopefully, Philemot, and will come along and have an answer for you.
