Google Analytics Multisite Async is a WordPress plugin by Dartur that lets the super admin collect statistics from all sites and it lets the regular site admins collect statistics from their own site. This means that statistics are collected to 2 different Analytics accounts at once, assuming that the site admin have entered an ID of course. It’s the asynchronous version of Analytics. There is a simple settings page that is only visible to the admins.
The plugin is localized and available in: english and swedish
