Registered User Own a Page?

I've used Drupal 4.3 and was satisfied with it. But now I have a couple of new projects that made me think to come back and evaluate the new version. I have to say I am VERY excited about the improvments and new features/mods. I've played around with the sf demo and read the docs and forums 'til my eyes fell out. I am still not clear on one thing.

Could a user, of a particular role, own/edit/comment ONLY ONE "static" page? Meaning, they log in and go to their own page and edit only it. NOT add stories to the page so it's not a blog type situation. Other registered folks, of a different role, could rate the page and add commentary. The page owner could then comment on the comments. But the page owners could not comment on other page owners page and/or comments. (whew!)

Is there a way already in place (sort of?) or could anyone give me some point of reference in terms of custom programming. I looked at taxonomy_access and that's not specific enough. I'm talking about 1,000's of pages (possibly) each with a unique owner.

node privacy by role says:
"This module, when enabled, allows each user of a site to decide which roles can view or view/edit a node."

How vague...
The each user gets me. I'm thinking that the admin(s) would assign one page to one user. Is this covered by this mod?

Will nodeperm_role do what I want? Thanks in advance.
