1. Approvals - Upon submitting a request for approval, the technician could simply choose "Requester's Manager".  SD+ would refer to the organization it fetches from AD.  This could be taken one step further by incorporating "Submit for approval" as an option in "Business rules".  Certain templates or request types could then be automatically submitted to the requester's manager for approval.
2. Escalation - SLA's could be configured to escalate to "Technician's Manager" whenever necessary.
3. I've had other ideas over time, but drawing a blank now... if you're reading this and you have other ideas, please post them here!!!!
