With Create Linked Issues & Linked Transition we did help you to bring teams of different JIRA projects closer together. However, the user still needed the appropriate permission in the project of the other team.
In JSU 2.1.0 you can configure a different user, who will create the new issue or trigger a transition on an existing one. Usually this will be a technical user with a lot of permissions, but no person logs into JIRA with it.

And back the from the developers to the support, trigger a transition on the support issue, whenever the developers task is done.
