If you have Chrome devices managed on your Google Apps domain you can manage chrome and the chrome webstore. In settings, chrome, user settings there is an option to deploy apps to chrome devices and also point users to 'for yourdomain' entry in the webstore. They will see this assuming they are signed into chrome with there domain account. So these settings result in this in the webstore: Apps that you don't already have will appear in the For yourdomain section. This makes it easy to users to find apps that you suggest. Seems to work well.
