Vista - RSAT Exchange tabs (Remote Server Administration Tools)

Does anyone know how to add the Exchange tabs to the "Active Directory Users
and Computers" snap-in once you have installed RSAT (Remote Server
Administration Tools).

For those of you who don't know what RSAT is:

RSAT replaces ADMINPAK.MSI. ADMINPAK installed the tools that allowed you to
administer Windows 2000 / 2003 server from a Windows XP box.

ADMINPAK did not install on Vista without all kind of extra work and even
then did perform as expected.

ADMINPAK has an add-in that you could download from Microsoft and install
that would allow you to view the Exchange tabs on individual account's within
the "Active Directory Users and Computers" snap-in.

My question is does anyone out there in the "Ether" know of any such add-on
for RSAT or are there any plans by Microsoft to create such a tool?
