Create a Faculty Directory and Allow Each Professor to Manage His/Her Own Page


I have a multisite install and would like to create a sub-site that would serve as a "Faculty Directory."

My question is very simple... but after spending the past week searching Google and testing a variety of plugins, it would appear the answer is not.

My idea is this:
1. Create a new page in the Faculty Directory called "Prof. X."
2. Add a new user, "Prof X," to the Faculty Directory.
3. Allow the user "Prof. X" to edit only the page entitled "Prof. X."

Is there a plugin that easily facilitates this? (If there is, I haven't found it.)

Again, I want a user to edit only one page. And I need to do this for about 80 users.

Thank you for your help.
