Mandriva Pulse 2 1.2.1 is available

It does. It is used in production in a 80000 machines French public service. It is also used in a #16000 machines environment, highly constrained, by people with no time for non working solutions.

It is the third architecture (LRS/Linbox Secure Control module which is used in French Ministère de l'Intérieur, Pulse 1 of Mandriva were the 2 first), and was designed to really handle huge installation. It is not a no limit software, but it tries to be.

Note : I work in Mandriva but not directly in Pulse2 team.
