One of the latest announcements out of Microsoft revolves yet again around SharePoint.  However, it also involve Microsoft Commerce Server 2009.  The two packages now have integration allowing you to more easily (I’ve gotten in trouble before for just saying easily, so I put the more condition in 🙂 create an ecommerce site built on SharePoint.  You can read more details at CMS Wire.  I haven’t tested it yet, but apparently there are several site templates, web parts, and other features that you get only when using the two products together.  It works with both MOSS and WSS, however, once again, you loose some functionality with WSS.  In fear of being repetitive, I won’t go into details.  Just click the link  earlier in this post and read all the details there.
