I have not heard of anything yet. I sort have thought of creating a sub
dashboard and then a new web part based on a link and point  it to the
CRM site. Have you tried that? I am curious as to what you thing the
web part would/should/could do as I am not sure what I would want it to
do even if I built a web part. Also are you looking at sps V2 or V1?

We are in the process of building some integration between Microsoft CRM
and Sharepoint V2.

We would be looking at V2. We would like a system to store service
orders and contracts and link them back to customers and or vendors in
CRM. I have been told that the newly released Business Portal runs off
of Share Point but I do not know if that as any integration with CRM or
not.

Have you seen Business Portal Yet? I have just looked at a few of the
links on the site. What exactly is it a portal for Great Plains?
