In regard to deploying the Fog Client have you played with the quiet install command/s yet?
As of version 0.29 and higher, the FOG client now supports a quiet installation mode. This can help automate deployments, by allowing the command to be run without user interaction from batch files. To do this the setup.exe file must be run from the command line with the arguments fog-defaults=true /qb.
So the full command would be:
setup.exe fog-defaults=true /qb
