All set the new version 0.2.3 has admin only privileges to the options page.
I was going to place in the ability to choose the user level access, but since you mentioned the employer / employee issue there is microdata for the employer/employee/founder.
This is a large project as variables would need to be added to the profile page. However I believe I can begin the project with a few items that are currently stored in the user area and add employee data to the microdata if wanted. This can also help with search results like "Store where Jen Works", or "Coffee Shop Mike Smith" to help with people who visited your business, remember an employee but don't remember where it was.
With this I would also include a user level access drop down, starting at admin when you first install but with the option to allow any user group access if you wish.
Thing is I wrote another plugin that imports your google webmaster tools into your admin panel so you can see the queries and pages without having to log into google webmaster tools. I'm just about finished and was planning on sending it in to wordpress today.
