Assigning customer service cases to partners?  We have a need to allow a customer to interact with their dealer (Partner community user) in submitting cases.  So it's a B2B2C relationship where we would assign the case to the correct partner based on the relationship between partner and end-customer.  So end customer would have access to a self-service portal, and cases can be submitted/routed to partner.  Does anyone have this implemented?  Are there any "gotchas"?
