As a preface, I know Foundation does not have audience targeting. But, I do not have an option to upgrade to SharePoint Server. So, with that preface, here is my dillema.
I have two SP groups, groupA and groupB. Both groups have access to list1, and I have a listview web part on a page for the users to query information. I would like to add a second listview web part for list2 on the same page. groupA does have permissions to read from list2 but groupB does not. Because both sets of users have the same roles, SPSecurity Trimming is not an option.
I would like to mimic audience targeting by hiding the listview web part for list2 if the user is not in groupA. Through SPServices I can retrieve a users groups, but I am not sure if there is a better approach to accomplish this task.
