I am currently evaluating Jira and it is the last point to confirm if our company will purchase it.... I would like the permission model supports "Reporter's Group". See the following examples will explain the reason why it is very helpful:

1) We have several products, e.g Product1, Product2 ....
Each product has its own component, version & release note
2) We support several dealers worldwide, e.g. Dealer1, Dealer2, ....
Each dealer is a "User Group" associating with a set of logins
4) We have a central support team for all dealers
5) However, it is critical that dealer should see ONLY his issues but not other dealers' issues

So, I will setup project like
Product 1 Support Area (with all component, version, release note setup properly)
Product 2 Support Area
....
However, the above cannot be achieved because there is no "Reporter's Group" permission for viewing the project

Because of the limitation, I need to create many project like:
Product 1 Support Area for Dealer 1
Product 1 Support Area for Dealer 2
....
Product 2 Support Area for Dealer 1
Product 2 Support Area for Dealer 2
....

And I need to duplicate all component, version & release note info into many projects. Also, the issue finder will be more difficult to use.

In fact, most IT companies have the similar workflow that they have several products & dealers .... but because of the sensivity of sales issues (some business deals cannot be seen by other dealers), all issues should be private to dealer group only. I wish Jira will support this. Many many thks.
