Commerce Server 2007 is available for download from the Microsoft site. There is a free evaluation version targetting developers who want to get started with it. The story of Commerce Server is a bit fuzzy to me. I don't see any plans in the
recent talks about the roadmap to bring the product on top of Windows SharePoint Services 2007 and delivered as a set of MOSS features and solutions, like the what happened with CMS.On the contrary, it seems that they move in the other direction and keep it apart from it. That's a pitty to my opinion. It would be nice to have a number of commerce-type of features (shopping basket, product catalogs, ...) available for MOSS 2007 to enrich for example the Internet sites you can build with it. My thinking is that if Microsoft is not going to offer this, one or more partners should build this. So, if you have time and money to invest :), go ahead and create an e-commerce MOSS 2007 site definition and dozens of little features that enable us to do e-commerce in our SharePoint sites. I am pretty sure it is going to be very profitable. Would love to hear if some partners are already thinking in that direction!
