BuddyPress.org

I have a lot of experience with custom post types, but within BuddyPress I believe the group functionality would be better.

Here is an example mockup:

For the above functionality, it would make sense to use a custom post type and a custom post screen within a users profile. However, using a variation of groups would instantly give me:

1. Ability for users to follow the vehicle (change members to followers)
2. A blog for the vehicle (using group blog)
3. Easy interface for users to manage their vehicles, I could quickly create admin pages for specifics (a page to specify capabilities, like range and speed, which would be used in the group listing page to filter vehicles)
4. If a vehicle were a university project, multiple “owners” could be specified.
5. I could use a task management plugin for vehicles

I’m not doing anything with vehicles, but I thought this would be a great example of using a variation of groups. I could also get this functionality through multisite and user blogs, with each vehicle being a blog with integrated theme and custom admin panel to match the user profile, but that is much, much more work and a really heavy implementation. It would allow each vehicle to be a powerful hub, but that’s beyond what I need.

Beyond that, I would also want to have groups used like on BuddyPress.org (Plugins vs themes), but I don’t want them to share a slug (/extend/plugins/ vs /extend/themes/).
