Hi Jason,
Not possible. You can setup Restricted SAM for the user. First disable all functions and then enable only DNS Administration for that user by running "sam -r".
This will not show all other screens to the user when he/she runs sam. However, still you will have to go through the "Networking and Communcation" Screen but it will be much easier.

You may be disappointed if you fail, but you are doomed if you don't try
