Output

Example output:

Package installation

From webserver
choco.exe Install firefox --source http://192.168.1.1:8080 -y

From fileshare (webserver is still needed for downloading the binaries!)
choco.exe Install firefox --source \\192.168.1.1\_deploy$\App_Data\Packages -y

I can recommend 'civetweb' as a simple webserver to deliver the binaries.

Alternative

Chocolatey's (business edition) own feature 'Package Internalizer'.
