We are working on an Intranet site and seem to be coming up against some inflexibility with permissions. I wanted to clarify in case I'm missing something:

Per menu management

Is it possible to allow a role permission to manage a specific menu? E.g. if HR have their own section on the site with their own side menu. I want users with an HR role to be able to manage that menu but not the main menu.

Post to specific Blog by role

Supposing a blog shared between several users, all of whom have a common role. Is it possible to assign that role permission to post/manage a specified blog. Currently I seem to be able to say a user can either manage their own blog or all blogs but not just a specific blog (not owned by them)?

Are either of these scenarios possible?

If you implement your own INavigationProvider you have complete control over what menu item gets rendered for the current user based on active permissions.

Out of the box I don't think it's possible to assign a role to a specific blog. But what you could do is write a content part that implements this requirement and attach it to the Blog content type.

Ultimately both scenarios are possible, but it requires custom coding.

Thanks will have a look at the content part for per role blogging.

I don't think I explained the menu management very clearly, it's not the displaying of menu items but rather the administration of a menu. Currently Orchard is all or nothing, you can either manage all of the menus or none. I want users to be be able to only have the ability to administrate a particular menu > so for example, the HR cms user can manage the HR menu but can't touch the main menu.
