Off-line Lion Server Software Update Server?

Scenario:
1 Private LAN(no internet Access) with a Mac Lion Server (latest version) and 6 laptop/desktops on the network and Remote Desktop Admin package

1 Remote location with Internet Access w/ Mac Lion Server and Software Update Server running.

I need the ability to export the files downloaded from the remote location and bring them to the private LAN and distribute them to the laptops, etc.

I am mostly a Windows Enterprise Admin so this is new to me. Microsoft has Software Update Service that I can export the files downloaded and metadata, transport them to the private LAN and import them into another Microsoft Software Update Server and distribute on the domain.

Is this possible on the MAC?
