Restricted access with custom messages for anonymous user a few other wishes

I’ve been looking for plugins for an extranet type solution. I have a few demands that I would really like:

1) I have pages (and perhaps posts) that I only want (some) logged in users to view (not to edit/contribute). For that I’ve found a few plugins. But I it would be great if the page also was visible (in the navigation/menu) to anonymous users (eg. not logged in). The information on the page – for the anonymous user – should be the login form, and really great if it could be possible to set a custom message/content per page basis.

2) Even more great if I could specify groups of users and granting access for specific groups. If a user wasn’t anonymous, but not a member of the right group, that user should be treated as an anonymous user on the specific page/post.

3) To make things easier setting access restriction on categories would be cool.

4) And to top it all it would be really really great if the access could be time limited, eg. the access to a specific page/post would automatically expire after the specified amount of time or on a specific date. Of course with an ‘never-expire’ option!

5) Perfect if I could set an custom message/content on accessing a page for which the granted access privilege has expired!

6) And in the future I imagine the need to view all granted access privileges per user basis. With information on expire time/date.

Do you know of any plugin that does all that??? Perhaps a few plugins? Or perhaps a plugin that does just some of it? Love to know about it!
