From my experience implementing, integrating or customizing different CRM solutions is that it's not like ERP or MRP. You can have a most optimal way of organizing your stocks, or managing your manufacturing process, and there can only be so many ways to look at the data (in terms of reporting) but CRM is about how you create a relationship with your customer and how to maintain it and every business IMHO requires slightly more customized approach and I believe the approach differ substantially between industries as well.
Cause 1 company owning the whole segment = monopolizing the industry. No?
