I’d like to implement Views that conditionally show or hide item listings of content nodes to the current User based on:
(1) value(s) in the current User’s profile and
(2) value(s) in the profile of the author of each item and
(3) value(s) in each content node itself.

A good example would be a classified ad system that enabled advertisers to specify that a given ad be shown only to users whose profiles meet a set of specific criteria.

For example: A Drupal site with User Accounts with custom fields to capture each user’s age, height, and hair, and a Content Type for advertisements with the same fields.

The challenge is how to construct a View that supports a use case like the following: Users who will look at the View:
= David is a bald, 6.5 foot, 70 yr old.
= Edward is a blond, 5’5″, 18 year old.
= Fred is a brown-haired, 5’11”, 30 year old.
Ads that can be displayed in the View as follows:
= “Miracle Grow Hair Spray” posted by Abby to be shown only to bald people.
= “NuEar Hearing Aids” posted by Betty to be shown only to people over age 65.
= “Big and Tall Shop” posted by Carol only to be shown to people over 6 feet tall.

In summary, I’m trying to filter tablular View of nodes based on attributes of the content nodes, the authors of the node, and the current user who is looking at the View.
The standard Views filter UI supports filters based on attributes of each node in the table, but does not appear to permit any use of information about the current user other than his login state.

Any advice and references to doing the filtering at the granularity of each node would be greatly appreciated!
