How will I license 'Applications' for JIRA 7?

[A9] William Kennedy

If 'Core' is licensed for 10000 users, but I have only 50 that need Portfolio, will I still be recommended to "Purchase the license tier that matches the number of users you have licensed for your host application"?

It seems like the new licensing model allows for more flexible deployment, in that I can allow access to Portfolio only from the Group who requires it.

Is this the case? Will I have a 10000 user 'Core' license, with another 10000 user license for 'Service Desk' also supporting my 50 Portfolio users and 500 Agile users?

A Marketplace FAQ update or other 'authoritative' source is much appreciated!

Update: Licensing model is changed a lot in JIRA 7. Please see @Nic Brough [Adaptavist]'s comments and examples in below. 

Yes it needs to match JIRA User licensing, that means if you have 10000 user JIRA license you should also purchase Portfolio for 10.000 users. Please check FAQ under Pricing tab of Portfolio page : https://marketplace.atlassian.com/plugins/com.radiantminds.roadmaps-JIRA

Only add-on that has different pricing model is Service Desk. It is based on agents not number of your JIRA users.
