Jeff -
Not that I know about...
If there was a best case for joint support it would have been the NetApp/Oracle team, but I've heard stories from customers with frustrations there recently.
In my new role at a VAR it's one of those areas where I can see us delivering on the 'Value Add' peice of the puzzle. We have our own support that will manage joint escalation cases with our vendors for our clients.
Good news - you have the community here to help ! What is the problem your client is having ? There are those here who'd like to try to solve your puzzle ...
I hope this response has been helpful to you.
At your service,
