Have any of you done a MS CRM 4.0 and SharePoint integration. Any Pointers? I am new to both the CRM and SharePoint. 

After a little more research, Id like to refine my question. I basically want to use IFRAME to add a SharePoint tab that will show the SharePoint page that I have created. Any hints on how to do that? 

Also how would I get access to the CRM data fields in SharePoint. i.e. if I add a file in SharePoint, I want it to have all the metadata from the CRM property page.
