Integrating multiple NAV databases with one CRM system

Hi,

We have an opportunity which involves integrating multiple NAV databases with one CRM installation. Has anyone ever done this and are there any pitfalls to avoid?

I have a URL that outlines the process and wondered if it is current or out of date?
