Instaling Unreal Engine Silently on OS X

Hello from Pratt Department of Digital Art:

We are huge fans of your program and would like to find how your software can be installed silently. We are running large program with 150 clients, and would love to install the software on all of the machine.

Couple of things of note. Each student will have their own Unreal login. Preferred way of installation is PKG file. Is this possible?
