Multi-seat licenses make it possible to link 2 or more accounts to:
Share DeskRoll licenses across accounts.
License sharing is convenient. The license is purchased from the Master account and it covers all the linked accounts.
Share unattended computers across accounts.
Share unattended computers across accounts. You can make accounts for some specific user categories, for example:
Therefore, each category has a separate login. Of course, you can keep specific machines to be accessible from the Master account only.
For example, you have an outsourcing partner who is providing remote deployment services for your project. They already use DeskRoll in-house, so you temporarily link their account to yours and give them access to the server to do the deployment jobs.
Once your partner has delivered, you unlink their account, therefore, revoking access to your machines. And they continue using DeskRoll in-house as they previously did.
