Our organization would also benefit from the ability to transfer attachments directly to JIRA. In large part this is because our developers do not have time to search through the ticket chains for the appropriate attachment when they are investigating an issue.

The ideal implementation for us would be that the Zendesk agent gets to choose which attachments are transferred to JIRA. A bulk transfer of all attachments would just lead to overwhelming clutter.

@all, my understanding was that the authentication to download option only requires that the person have a zendesk account. It does not require that they have agent status. While it's not ideal, couldn't your developers create end-user accounts in your support portal so that they can then download files using the secure links.
