Totara is a distribution of the free/open source LMS Moodle, aimed at Kineo’s corporate clients: I’m sure that it’s aimed to attract new clients, as well as to serve current clients.
Since Moodle is under the GPL, so is Totara. That means that when you get Totara, you get its source code, and are free to modify and redistribute your modifications. (It means more than that, but that’s enough about the GPL for this post.)
I plan to try out Totara when it becomes available. It looks as though that means January 2011. The LMS I’m trying out right now is Schoology, about which I posted last week.
