Jeff Currier just posted this blog post where he talks about using cURL with SSDS.  This illustrates why we are taking an incremental approach.  Using cURL with SSDS was not even on our radar till one of the first customers to go on the "restricted beta" wanted to use this.  Jeff dug into it and helped them along.  Now he is sharing this out with everyone else.  When we started down this path, we were willing to be surprised.  This is one of them.  I am sure many more are on the way.
