How do I determine who has access to modify an active directory group

I'm working on creating an administrative interface that allows managing users in groups in Active Directory.

I would like to only show groups to the active user if the user actually has the rights to add or remove other users within those groups, but I'm not sure at this point, how to determine which people can modify the groups, or whether the current person has access to modify a specific group.

I suppose the application can find out after the user tries and we get an access error, but I don't like to use error trapping as a way of determining if some feature is available and I would prefer not to tempt the users with a list of groups they can't control.

If possible, please supply an answer that targets vb.net 3.5 using System.DirectoryServices.AccountManagement as that is the environment that I am currently working within. I can translate from C# if necessary.
