Finding all groups a user is a member of

The question does not pertain to one level deep hierarchies [1], but to nested groups (ie Joe is an administrator and thus member in the group Administrators; this group is member in say SharepointA group [and so on])

What is the recommended way of querying this?

var groupReferences = dataService.LoadProperty(user, "MemberOf")                    
 .OfType<ReferencedObject>()
 .Where(r => r.ObjectType == "Group")
 .Select(g => g.ObjectId);
