Optimize AD Groups for Contact Lists

Smartphones, Contact Collections and the Global Address List
There are many elegant things about Active Directory. One thing that has always impressed me is the simplicity, reliability and scalability of AD Groups. When constructing groups, it is trivial to insert mailboxes, contacts or domain users as members of a group. We also have the flexibility to nest groups inside of groups. When we ultimately send an email to a distribution group, the expansion happens on the server and can recursively include dozens or even hundreds of groups and thousands of recipient objects.
