Alternatives to OF, with shared projects?
 

I showed OF for a client, and they got really interested.
However, they want a project manager that they can share between the employees as well as keeping personal projects. And also having iPhone and iPad apps.
This means that OF doesn't suit them, since it doesn't have a shared projects feature (which I think would be a killer feature).

So, is there an application that have:
- Mac app
- iPad app
- iPhone app
- Personal project management
- Shared project management
?

Ie, just as OF but with Shared project management as well...!

OmniPlan provides shared project management in a Mac app and soon an iPad app. We're thinking about how to integrate OmniFocus with it someday.

Thanks for that Lizard!
