Set arithmetic with SharePoint groups

Question

Is it possible to perform set arithmetic on sharepoint groups?

An example situation is audiencing.

I want the web part to display to all in group A who do not also belong to group B. And on that page, another web part is to be displayed to group B.

I figure this isnt possible as I cant find a source on it, but I thought id ask people who no doubt have more experience with this than I do.

Thanks.

It seems even with complex programming (http://msdn.microsoft.com/en-us/library/ms578007.aspx) does not allow you to create the rule because with membership, the only operator I know of is "Member of". See if following helps:

Create three group names and put people in right groups:

Coders (Set A)

Managers (Set B)

Managers who can write code (Intersection of Set A and Set B)

Audience 1 (Rules below):

user belong to Coders

Audience 2 [ Rules below]

User belong to Managers

Or [in UI this corresponds to Satisfy any of the rules]

Users belong to Managers who can write code

Target WebPart 1 to Audience 1 and WebPart 2 to Audience 2

Answer 2

You're in luck. This isn't available OOTB but Waldek has just released a post on Negated Audiences
