I agree with the impression that SharePoint is perceived as all things to all men and I believe that this is largely attributable to the diverse range of capabilities it encompasses. In my view, asking "what is the business solution SharePoint provides" is like asking "what is the business solution Windows 2008 Server provides". It certainly has some major shortcomings in the DM context, but it has to be said that the vast majority of those (unique referencing, copying/linking, deduplication, and metadata profile inheritance) are actually fairly easily resolved within its customization framework. I only know Handshake reasonably superficially, and it certainly seems to provide some interesting capabilities to *integrate* with existing DM systems. But if your objective is to use SharePoint for DM and you have more than a couple of hundred users, even at £99/seat it starts to look expensive compared to just solving the limitations directly. I know that there's the maintenance questions, but TCO-wise DM Director does seem to be exploiting a lack of understanding and expertise - very wise and intelligent of them, but not so great for the customer. I wish the "techies in Tallahasse" good luck - their first mover advantage deserves credit. But I think that soon customers will find the people who know how to solve the real business problems with SharePoint and many of these technical limitations will be put into context.
